Given numbers are 640, 457, 751, 694
The list of prime factors of all numbers are
Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5
Prime factors of 457 are 457
Prime factors of 751 are 751
Prime factors of 694 are 2 x 347
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 640, 457, 751, 694
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 457) = 292480
GCD(640, 457) = ( 640 x 457 ) / 292480
= 640 / 457
= 640
Step2:
LCM(1, 751) = 751
GCD(1, 751) = ( 1 x 751 ) / 751
= 1 / 751
= 1
Step3:
LCM(1, 694) = 694
GCD(1, 694) = ( 1 x 694 ) / 694
= 1 / 694
= 1
So, Greatest Common Divisor of 640, 457, 751, 694 is 1
