Given numbers are 822, 207, 921, 538
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(822, 207) = 56718
GCD(822, 207) = ( 822 x 207 ) / 56718
= 822 / 207
= 822
Step2:
LCM(3, 921) = 921
GCD(3, 921) = ( 3 x 921 ) / 921
= 3 / 921
= 3
Step3:
LCM(3, 538) = 1614
GCD(3, 538) = ( 3 x 538 ) / 1614
= 3 / 538
= 3
So, Greatest Common Divisor of 822, 207, 921, 538 is 1
