GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(249, 628) = 156372
GCD(249, 628) = ( 249 x 628 ) / 156372
= 249 / 628
= 249
Step2:
LCM(1, 167) = 167
GCD(1, 167) = ( 1 x 167 ) / 167
= 1 / 167
= 1
Step3:
LCM(1, 640) = 640
GCD(1, 640) = ( 1 x 640 ) / 640
= 1 / 640
= 1
So, Greatest Common Divisor of 249, 628, 167, 640 is 1
