GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(387, 148) = 57276
GCD(387, 148) = ( 387 x 148 ) / 57276
= 387 / 148
= 387
Step2:
LCM(1, 226) = 226
GCD(1, 226) = ( 1 x 226 ) / 226
= 1 / 226
= 1
Step3:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
So, Greatest Common Divisor of 387, 148, 226, 639 is 1
