That would depend on yields. Also simply killing all humans would take much much less.
Russia has over 55000 nuclear warheads. Massive production occurred mainly after the 9/11 attack on U.S. soil. Many believe it to be in preparation for a 3rd World War.
It would not take all the world's nuclear missiles to destroy the world as it only takes a few well-placed ones to cause catastrophic damage. The exact number is hard to determine, as it would depend on various factors such as the target locations and the size of the warheads. Just a small fraction of the world's nuclear arsenal could potentially cause widespread devastation.
It is estimated that there are currently around 13,400 nuclear warheads in the world, with a total explosive yield of approximately 4,000 megatons. These warheads are owned by various countries such as the United States, Russia, China, and others.
It is estimated that there are around 13,410 nuclear warheads worldwide, with the vast majority being in the arsenals of the United States and Russia. This includes both hydrogen bombs and other types of nuclear weapons.
To destroy the planet (as in blow it into pieces), no. But to destroy all live on the surface, yes.
About 30,000.
There hasn't been a test on that yet, it would also depend on how big the warheads carried were.

over 9000
It is difficult to determine an exact number of nuclear warheads needed to end all life on Earth as it would depend on various factors such as targeting and the size of the warheads. However, it is believed that even a small fraction of the world's nuclear arsenal could potentially cause catastrophic global consequences.
In the late 1980s it peaked at somewhere over 20,000 warheads. As of 2012 the total has declined to roughly 10,000 warheads.
Destroy its cache of nuclear warheads
China is estimated to have around 320 nuclear warheads in its arsenal, according to the Stockholm International Peace Research Institute (SIPRI).
In theory, you can't destroy something and then destroy it again...
Around 400 nuclear warheads. China has the third largest nuclear arsenal in the world.
No one knows, but more than 100,000 were built, and we know that US & Russia admit to 28,800.
Soon after World War 2 rockets were used to carry nuclear warheads. In the space program they are used to carry many kinds of objects into space. But, they are still used to carry nuclear warheads too.
