Given numbers are 644, 577, 392, 895

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

Apply this formula for all numbers.

Step1:

LCM(644, 577) = 371588

GCD(644, 577) = ( 644 x 577 ) / 371588

= 644 / 577

= 644

Step2:

LCM(1, 392) = 392

GCD(1, 392) = ( 1 x 392 ) / 392

= 1 / 392

= 1

Step3:

LCM(1, 895) = 895

GCD(1, 895) = ( 1 x 895 ) / 895

= 1 / 895

= 1

So, Greatest Common Divisor of 644, 577, 392, 895 is 1
