Prime factors of 107 are 107
Prime factors of 490 are 2 x 5 x 7 x 7
Prime factors of 645 are 3 x 5 x 43
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 252, 107, 490, 645
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(252, 107) = 26964
GCD(252, 107) = ( 252 x 107 ) / 26964
= 252 / 107
= 252
Step2:
LCM(1, 490) = 490
GCD(1, 490) = ( 1 x 490 ) / 490
= 1 / 490
= 1
Step3:
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
= 1 / 645
= 1
So, Greatest Common Divisor of 252, 107, 490, 645 is 1
