Given numbers are 647, 554, 828, 481

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

Apply this formula for all numbers.

Step1:

LCM(647, 554) = 358438

GCD(647, 554) = ( 647 x 554 ) / 358438

= 647 / 554

= 647

Step2:

LCM(1, 828) = 828

GCD(1, 828) = ( 1 x 828 ) / 828

= 1 / 828

= 1

Step3:

LCM(1, 481) = 481

GCD(1, 481) = ( 1 x 481 ) / 481

= 1 / 481

= 1

So, Greatest Common Divisor of 647, 554, 828, 481 is 1
