Given numbers are 722, 690, 325, 129
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(722, 690) = 249090
GCD(722, 690) = ( 722 x 690 ) / 249090
= 722 / 690
= 722
Step2:
LCM(2, 325) = 650
GCD(2, 325) = ( 2 x 325 ) / 650
= 2 / 325
= 2
Step3:
LCM(1, 129) = 129
GCD(1, 129) = ( 1 x 129 ) / 129
= 1 / 129
= 1
So, Greatest Common Divisor of 722, 690, 325, 129 is 1
