Given numbers are 157, 387, 643, 650
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(157, 387) = 60759
GCD(157, 387) = ( 157 x 387 ) / 60759
= 157 / 387
= 157
Step2:
LCM(1, 643) = 643
GCD(1, 643) = ( 1 x 643 ) / 643
= 1 / 643
= 1
Step3:
LCM(1, 650) = 650
GCD(1, 650) = ( 1 x 650 ) / 650
= 1 / 650
= 1
So, Greatest Common Divisor of 157, 387, 643, 650 is 1
