Given numbers are 637, 810, 220, 752
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(637, 810) = 515970
GCD(637, 810) = ( 637 x 810 ) / 515970
= 637 / 810
= 637
Step2:
LCM(1, 220) = 220
GCD(1, 220) = ( 1 x 220 ) / 220
= 1 / 220
= 1
Step3:
LCM(1, 752) = 752
GCD(1, 752) = ( 1 x 752 ) / 752
= 1 / 752
= 1
So, Greatest Common Divisor of 637, 810, 220, 752 is 1
