The GCF is 70.The GCF is 70.
hcf(490, 1750) = 70 Using factorisation: 490 = 2 x 5 x 7² 1750 = 2 x 5³ x 7 hcf = 2 x 5 x 7 = 70
The Highest Common Factor (HCF) of 280 and 180 is the largest positive integer that divides both numbers without leaving a remainder. To find the HCF, you can use the Euclidean algorithm or prime factorization method. In this case, the prime factorization of 280 is 2^3 * 5 * 7 and the prime factorization of 180 is 2^2 * 3^2 * 5. The common factors between the two numbers are 2^2 and 5, so the HCF of 280 and 180 is 20.

490
The GCF is 70.
The GCF is 70.The GCF is 70.
the answer is 49
Factor them both. 2 x 5 x 7 x 7 = 490 2 x 2 x 2 x 5 x 7 + 280 Find the factors in common. 2 x 5 x 7 = 70, the HCF
The highest common factor of the numbers 490 and 630 is 70.

140, 280, 490, yes. 230, 330, 610, no.
HCF(140, 490) = 70 So 70 and any factor of 70 will do.
Their HCF is 8
The GCF is 70.
You don't. You need at least two numbers to find a GCF.
