The list of prime factors of all numbers are
Prime factors of 670 are 2 x 5 x 67
Prime factors of 731 are 17 x 43
Prime factors of 42 are 2 x 3 x 7
Prime factors of 102 are 2 x 3 x 17
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 670, 731, 42, 102
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(670, 731) = 489770
GCD(670, 731) = ( 670 x 731 ) / 489770
= 670 / 731
= 670
Step2:
LCM(1, 42) = 42
GCD(1, 42) = ( 1 x 42 ) / 42
= 1 / 42
= 1
Step3:
LCM(1, 102) = 102
GCD(1, 102) = ( 1 x 102 ) / 102
= 1 / 102
= 1
So, Greatest Common Divisor of 670, 731, 42, 102 is 1
