2 is a fraction of both 18 & 10
The highest common factor of 10 and 18 is 2.
The greatest common multiple of 10 and 18 is infinite.However, I suspect you want either:the greatest common factor of 10 and 18 which is the largest number which divides both 10 and 18 and is 2; orthe lowest common multiple of 10 and 18 which is smallest number into which both 10 and 18 divide (ie the smallest number which is a multiple of both 10 and 18) and is 90
Least Common Multiple (LCM) for 10 18 9 is 90
The Least Common Multiple (LCM) for 10 18 30 is 90.
The least common multiple of 3, 10, and 18 is 90.
The least common multiple of the numbers 29, 18 and 10 is 2,610.
The least common multiple of the numbers 20, 18 and 10 is 180.
The greatest common factor of 10 and 18 is 2. The factors of 10 are 1, 2, 5 and 10 The factors of 18 are 1, 2, 3, 6, 9, and 18 So the GCF is 2.
The LCM of 9, 10, and 18 is 90.
lcm(6, 10, 18) = 90
The GCF of 10, 18, and 24 is 2.
90 is the lowest common multiple of 18, 10 and 5.
