Given numbers are 644, 772, 544, 697

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

Apply this formula for all numbers.

Step1:

LCM(644, 772) = 124292

GCD(644, 772) = ( 644 x 772 ) / 124292

= 644 / 772

= 644

Step2:

LCM(4, 544) = 544

GCD(4, 544) = ( 4 x 544 ) / 544

= 4 / 544

= 4

Step3:

LCM(4, 697) = 2788

GCD(4, 697) = ( 4 x 697 ) / 2788

= 4 / 697

= 4

So, Greatest Common Divisor of 644, 772, 544, 697 is 1
