Given numbers are 661, 748, 142, 119
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(661, 748) = 494428
GCD(661, 748) = ( 661 x 748 ) / 494428
= 661 / 748
= 661
Step2:
LCM(1, 142) = 142
GCD(1, 142) = ( 1 x 142 ) / 142
= 1 / 142
= 1
Step3:
LCM(1, 119) = 119
GCD(1, 119) = ( 1 x 119 ) / 119
= 1 / 119
= 1
So, Greatest Common Divisor of 661, 748, 142, 119 is 1
