Given numbers are 721, 658, 379, 495
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(721, 658) = 67774
GCD(721, 658) = ( 721 x 658 ) / 67774
= 721 / 658
= 721
Step2:
LCM(7, 379) = 2653
GCD(7, 379) = ( 7 x 379 ) / 2653
= 7 / 379
= 7
Step3:
LCM(1, 495) = 495
GCD(1, 495) = ( 1 x 495 ) / 495
= 1 / 495
= 1
So, Greatest Common Divisor of 721, 658, 379, 495 is 1
