Given numbers are 644, 576, 77, 730

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

Apply this formula for all numbers.

Step1:

LCM(644, 576) = 92736

GCD(644, 576) = ( 644 x 576 ) / 92736

= 644 / 576

= 644

Step2:

LCM(4, 77) = 308

GCD(4, 77) = ( 4 x 77 ) / 308

= 4 / 77

= 4

Step3:

LCM(1, 730) = 730

GCD(1, 730) = ( 1 x 730 ) / 730

= 1 / 730

= 1

So, Greatest Common Divisor of 644, 576, 77, 730 is 1
