Given numbers are 325, 426, 646, 680
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(325, 426) = 138450
GCD(325, 426) = ( 325 x 426 ) / 138450
= 325 / 426
= 325
Step2:
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
= 1 / 646
= 1
Step3:
LCM(1, 680) = 680
GCD(1, 680) = ( 1 x 680 ) / 680
= 1 / 680
= 1
So, Greatest Common Divisor of 325, 426, 646, 680 is 1
