Given numbers are 381, 318, 391, 435
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(381, 318) = 40386
GCD(381, 318) = ( 381 x 318 ) / 40386
= 381 / 318
= 381
Step2:
LCM(3, 391) = 1173
GCD(3, 391) = ( 3 x 391 ) / 1173
= 3 / 391
= 3
Step3:
LCM(1, 435) = 435
GCD(1, 435) = ( 1 x 435 ) / 435
= 1 / 435
= 1
So, Greatest Common Divisor of 381, 318, 391, 435 is 1
