Given numbers are 756, 630, 728, 558

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(756, 630) = 3780

GCD(756, 630) = ( 756 x 630 ) / 3780

= 756 / 630

= 756

Step2:

LCM(126, 728) = 6552

GCD(126, 728) = ( 126 x 728 ) / 6552

= 126 / 728

= 126

Step3:

LCM(14, 558) = 3906

GCD(14, 558) = ( 14 x 558 ) / 3906

= 14 / 558

= 14

So, Greatest Common Divisor of 756, 630, 728, 558 is 2
