Given numbers are 687, 573, 810, 124
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(687, 573) = 131217
GCD(687, 573) = ( 687 x 573 ) / 131217
= 687 / 573
= 687
Step2:
LCM(3, 810) = 810
GCD(3, 810) = ( 3 x 810 ) / 810
= 3 / 810
= 3
Step3:
LCM(3, 124) = 372
GCD(3, 124) = ( 3 x 124 ) / 372
= 3 / 124
= 3
So, Greatest Common Divisor of 687, 573, 810, 124 is 1
