Given numbers are 124, 724, 274, 821
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(124, 724) = 22444
GCD(124, 724) = ( 124 x 724 ) / 22444
= 124 / 724
= 124
Step2:
LCM(4, 274) = 548
GCD(4, 274) = ( 4 x 274 ) / 548
= 4 / 274
= 4
Step3:
LCM(2, 821) = 1642
GCD(2, 821) = ( 2 x 821 ) / 1642
= 2 / 821
= 2
So, Greatest Common Divisor of 124, 724, 274, 821 is 1
