What is the HCF of 2 and 4?
In these types of problems, the numbers can also be the answer. 6 and 72 have a GCF of 6 and an LCM of 72. Since the product of the GCF and LCM of two numbers is the same …as the product of the numbers, you could also use another factor pair of 432, like 18 and 24.
The idea is to divide 274170 by 17017, and get the remainder. In this case, the answer is 1898. This means that the greatest common factor of 274170 and 17017 is the same as t…he greatest common factor of 17017 and 1898. Continue this process (next step: divide 17017 by 1898, and get the remainder), until you get two numbers, one of which is a multiple of the other one. In this case, the smaller of the two number is the greatest common factor.
In order to have a LCM of 30, the two numbers must only have unique primes that multiply to give 30. 30 is the product of 2, 3 and 5. To have an HCF of 2, the two numbers …must only share a factor of 2. Thus the factors of one must be 2 and 3, and the factors of the other must be 2 and 5: 2x3 = 6 2x5 = 10 Therefore the two numbers with an HCF of 2 and an LCM of 30 are 6 and 10. or 2 and 30
The HCF is 1.
No. The prime factors of 140 are 2,2,5 and 7 The prime factors of 210 are 2,3,5 and 7 The common prime factors are 2,5 and 7 Thus the HCF is 2x5x7, or 70.
The HCF of 4 and 5 is 1.
11 and 22, among others.
2 and 0 do not have a Highest Common Factor. This is because no number goes into 0.
The GCF is 2.
2 and 24 6 and 8
You need at least two numbers to find an HCF.
2 and 20 have an HCF of 2 and an LCM of 20. You could also use 4 and 10.
4 and 48 can. So can 12 and 16.
