Given numbers are 644, 612, 202, 797

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

Apply this formula for all numbers.

Step1:

LCM(644, 612) = 98532

GCD(644, 612) = ( 644 x 612 ) / 98532

= 644 / 612

= 644

Step2:

LCM(4, 202) = 404

GCD(4, 202) = ( 4 x 202 ) / 404

= 4 / 202

= 4

Step3:

LCM(2, 797) = 1594

GCD(2, 797) = ( 2 x 797 ) / 1594

= 2 / 797

= 2

So, Greatest Common Divisor of 644, 612, 202, 797 is 1
