Given numbers are 756, 291, 641, 816

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

Apply this formula for all numbers.

Step1:

LCM(756, 291) = 73332

GCD(756, 291) = ( 756 x 291 ) / 73332

= 756 / 291

= 756

Step2:

LCM(3, 641) = 1923

GCD(3, 641) = ( 3 x 641 ) / 1923

= 3 / 641

= 3

Step3:

LCM(1, 816) = 816

GCD(1, 816) = ( 1 x 816 ) / 816

= 1 / 816

= 1

So, Greatest Common Divisor of 756, 291, 641, 816 is 1
