GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(756, 792) = 16632
GCD(756, 792) = ( 756 x 792 ) / 16632
= 756 / 792
= 756
Step2:
LCM(36, 490) = 8820
GCD(36, 490) = ( 36 x 490 ) / 8820
= 36 / 490
= 36
Step3:
LCM(2, 620) = 620
GCD(2, 620) = ( 2 x 620 ) / 620
= 2 / 620
= 2
So, Greatest Common Divisor of 756, 792, 490, 620 is 2
