Given numbers are 756, 648, 435, 404
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(756, 648) = 4536
GCD(756, 648) = ( 756 x 648 ) / 4536
= 756 / 648
= 756
Step2:
LCM(108, 435) = 15660
GCD(108, 435) = ( 108 x 435 ) / 15660
= 108 / 435
= 108
Step3:
LCM(3, 404) = 1212
GCD(3, 404) = ( 3 x 404 ) / 1212
= 3 / 404
= 3
So, Greatest Common Divisor of 756, 648, 435, 404 is 1
