Given numbers are 765, 438, 401, 956
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(765, 438) = 111690
GCD(765, 438) = ( 765 x 438 ) / 111690
= 765 / 438
= 765
Step2:
LCM(3, 401) = 1203
GCD(3, 401) = ( 3 x 401 ) / 1203
= 3 / 401
= 3
Step3:
LCM(1, 956) = 956
GCD(1, 956) = ( 1 x 956 ) / 956
= 1 / 956
= 1
So, Greatest Common Divisor of 765, 438, 401, 956 is 1
