Given numbers are 398, 332, 823, 651
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 332) = 66068
GCD(398, 332) = ( 398 x 332 ) / 66068
= 398 / 332
= 398
Step2:
LCM(2, 823) = 1646
GCD(2, 823) = ( 2 x 823 ) / 1646
= 2 / 823
= 2
Step3:
LCM(1, 651) = 651
GCD(1, 651) = ( 1 x 651 ) / 651
= 1 / 651
= 1
So, Greatest Common Divisor of 398, 332, 823, 651 is 1
