Given numbers are 798, 756, 21, 136

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

Apply this formula for all numbers.

Step1:

LCM(798, 756) = 14364

GCD(798, 756) = ( 798 x 756 ) / 14364

= 798 / 756

= 798

Step2:

LCM(42, 21) = 42

GCD(42, 21) = ( 42 x 21 ) / 42

= 42 / 21

= 42

Step3:

LCM(21, 136) = 2856

GCD(21, 136) = ( 21 x 136 ) / 2856

= 21 / 136

= 21

So, Greatest Common Divisor of 798, 756, 21, 136 is 1
