Given numbers are 651, 221, 279, 842
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(651, 221) = 143871
GCD(651, 221) = ( 651 x 221 ) / 143871
= 651 / 221
= 651
Step2:
LCM(1, 279) = 279
GCD(1, 279) = ( 1 x 279 ) / 279
= 1 / 279
= 1
Step3:
LCM(1, 842) = 842
GCD(1, 842) = ( 1 x 842 ) / 842
= 1 / 842
= 1
So, Greatest Common Divisor of 651, 221, 279, 842 is 1
