GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(615, 847) = 520905
GCD(615, 847) = ( 615 x 847 ) / 520905
= 615 / 847
= 615
Step2:
LCM(1, 748) = 748
GCD(1, 748) = ( 1 x 748 ) / 748
= 1 / 748
= 1
Step3:
LCM(1, 961) = 961
GCD(1, 961) = ( 1 x 961 ) / 961
= 1 / 961
= 1
So, Greatest Common Divisor of 615, 847, 748, 961 is 1
