GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(630, 858) = 90090
GCD(630, 858) = ( 630 x 858 ) / 90090
= 630 / 858
= 630
Step2:
LCM(6, 308) = 924
GCD(6, 308) = ( 6 x 308 ) / 924
= 6 / 308
= 6
Step3:
LCM(2, 434) = 434
GCD(2, 434) = ( 2 x 434 ) / 434
= 2 / 434
= 2
So, Greatest Common Divisor of 630, 858, 308, 434 is 2
