Given numbers are 422, 987, 375, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(422, 987) = 416514
GCD(422, 987) = ( 422 x 987 ) / 416514
= 422 / 987
= 422
Step2:
LCM(1, 375) = 375
GCD(1, 375) = ( 1 x 375 ) / 375
= 1 / 375
= 1
Step3:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
So, Greatest Common Divisor of 422, 987, 375, 257 is 1
