Given numbers are 647, 790, 578, 452

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

Apply this formula for all numbers.

Step1:

LCM(647, 790) = 511130

GCD(647, 790) = ( 647 x 790 ) / 511130

= 647 / 790

= 647

Step2:

LCM(1, 578) = 578

GCD(1, 578) = ( 1 x 578 ) / 578

= 1 / 578

= 1

Step3:

LCM(1, 452) = 452

GCD(1, 452) = ( 1 x 452 ) / 452

= 1 / 452

= 1

So, Greatest Common Divisor of 647, 790, 578, 452 is 1
