Given numbers are 961, 145, 113, 658
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(961, 145) = 139345
GCD(961, 145) = ( 961 x 145 ) / 139345
= 961 / 145
= 961
Step2:
LCM(1, 113) = 113
GCD(1, 113) = ( 1 x 113 ) / 113
= 1 / 113
= 1
Step3:
LCM(1, 658) = 658
GCD(1, 658) = ( 1 x 658 ) / 658
= 1 / 658
= 1
So, Greatest Common Divisor of 961, 145, 113, 658 is 1
