Given numbers are 642, 822, 853, 461
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 822) = 87954
GCD(642, 822) = ( 642 x 822 ) / 87954
= 642 / 822
= 642
Step2:
LCM(6, 853) = 5118
GCD(6, 853) = ( 6 x 853 ) / 5118
= 6 / 853
= 6
Step3:
LCM(1, 461) = 461
GCD(1, 461) = ( 1 x 461 ) / 461
= 1 / 461
= 1
So, Greatest Common Divisor of 642, 822, 853, 461 is 1
