Given numbers are 658, 136, 129, 140
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(658, 136) = 44744
GCD(658, 136) = ( 658 x 136 ) / 44744
= 658 / 136
= 658
Step2:
LCM(2, 129) = 258
GCD(2, 129) = ( 2 x 129 ) / 258
= 2 / 129
= 2
Step3:
LCM(1, 140) = 140
GCD(1, 140) = ( 1 x 140 ) / 140
= 1 / 140
= 1
So, Greatest Common Divisor of 658, 136, 129, 140 is 1
