Given numbers are 630, 914, 377, 646
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(630, 914) = 287910
GCD(630, 914) = ( 630 x 914 ) / 287910
= 630 / 914
= 630
Step2:
LCM(2, 377) = 754
GCD(2, 377) = ( 2 x 377 ) / 754
= 2 / 377
= 2
Step3:
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
= 1 / 646
= 1
So, Greatest Common Divisor of 630, 914, 377, 646 is 1
