The list of prime factors of all numbers are
Prime factors of 755 are 5 x 151
Prime factors of 700 are 2 x 2 x 5 x 5 x 7
Prime factors of 638 are 2 x 11 x 29
Prime factors of 831 are 3 x 277
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 755, 700, 638, 831
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(755, 700) = 105700
GCD(755, 700) = ( 755 x 700 ) / 105700
= 755 / 700
= 755
Step2:
LCM(5, 638) = 3190
GCD(5, 638) = ( 5 x 638 ) / 3190
= 5 / 638
= 5
Step3:
LCM(1, 831) = 831
GCD(1, 831) = ( 1 x 831 ) / 831
= 1 / 831
= 1
So, Greatest Common Divisor of 755, 700, 638, 831 is 1
