Given numbers are 670, 174, 770, 251
The list of prime factors of all numbers are
Prime factors of 670 are 2 x 5 x 67
Prime factors of 174 are 2 x 3 x 29
Prime factors of 770 are 2 x 5 x 7 x 11
Prime factors of 251 are 251
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 670, 174, 770, 251
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(670, 174) = 58290
GCD(670, 174) = ( 670 x 174 ) / 58290
= 670 / 174
= 670
Step2:
LCM(2, 770) = 770
GCD(2, 770) = ( 2 x 770 ) / 770
= 2 / 770
= 2
Step3:
LCM(2, 251) = 502
GCD(2, 251) = ( 2 x 251 ) / 502
= 2 / 251
= 2
So, Greatest Common Divisor of 670, 174, 770, 251 is 1
