GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 822) = 163578
GCD(398, 822) = ( 398 x 822 ) / 163578
= 398 / 822
= 398
Step2:
LCM(2, 276) = 276
GCD(2, 276) = ( 2 x 276 ) / 276
= 2 / 276
= 2
Step3:
LCM(2, 921) = 1842
GCD(2, 921) = ( 2 x 921 ) / 1842
= 2 / 921
= 2
So, Greatest Common Divisor of 398, 822, 276, 921 is 1
