Given numbers are 932, 912, 645, 684
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(932, 912) = 212496
GCD(932, 912) = ( 932 x 912 ) / 212496
= 932 / 912
= 932
Step2:
LCM(4, 645) = 2580
GCD(4, 645) = ( 4 x 645 ) / 2580
= 4 / 645
= 4
Step3:
LCM(1, 684) = 684
GCD(1, 684) = ( 1 x 684 ) / 684
= 1 / 684
= 1
So, Greatest Common Divisor of 932, 912, 645, 684 is 1
