Given numbers are 430, 272, 391, 381
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(430, 272) = 58480
GCD(430, 272) = ( 430 x 272 ) / 58480
= 430 / 272
= 430
Step2:
LCM(2, 391) = 782
GCD(2, 391) = ( 2 x 391 ) / 782
= 2 / 391
= 2
Step3:
LCM(1, 381) = 381
GCD(1, 381) = ( 1 x 381 ) / 381
= 1 / 381
= 1
So, Greatest Common Divisor of 430, 272, 391, 381 is 1
