GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(788, 371) = 292348
GCD(788, 371) = ( 788 x 371 ) / 292348
= 788 / 371
= 788
Step2:
LCM(1, 885) = 885
GCD(1, 885) = ( 1 x 885 ) / 885
= 1 / 885
= 1
Step3:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
So, Greatest Common Divisor of 788, 371, 885, 639 is 1
