Given numbers are 157, 391, 478, 368
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(157, 391) = 61387
GCD(157, 391) = ( 157 x 391 ) / 61387
= 157 / 391
= 157
Step2:
LCM(1, 478) = 478
GCD(1, 478) = ( 1 x 478 ) / 478
= 1 / 478
= 1
Step3:
LCM(1, 368) = 368
GCD(1, 368) = ( 1 x 368 ) / 368
= 1 / 368
= 1
So, Greatest Common Divisor of 157, 391, 478, 368 is 1
