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 GCF is 30.
3.
The HCF of 30 and 105 is 15.
The GCF is 3.
The HCF/GCF of 385 and 210 is 35.
Prime factors of 210 are: 2, 3, 5 and 7 Prime factors of 385 are: 5,7 and 11 Common factors are: 5 and 7 and so 5*7 = 35 which is the hcf
The GCF is 30.
HCF = 14
The GCF is 1.
The GCF is 42.

35. 350 = 2 x 52 x 7 385 = 5 x 7 x 11 hcf = 5 x 7 = 35
The highest common factor (HCF) of 210 and 308 is the largest positive integer that divides both 210 and 308 without leaving a remainder. To find the HCF, you can use the Euclidean algorithm or prime factorization method. By prime factorizing 210 (2 x 3 x 5 x 7) and 308 (2 x 2 x 7 x 11), you can identify the common prime factors, which are 2 and 7. Therefore, the HCF of 210 and 308 is 14.
The GCF is 14.
