GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(249, 279) = 23157
GCD(249, 279) = ( 249 x 279 ) / 23157
= 249 / 279
= 249
Step2:
LCM(3, 662) = 1986
GCD(3, 662) = ( 3 x 662 ) / 1986
= 3 / 662
= 3
Step3:
LCM(1, 220) = 220
GCD(1, 220) = ( 1 x 220 ) / 220
= 1 / 220
= 1
So, Greatest Common Divisor of 249, 279, 662, 220 is 1
