Given numbers are 622, 630, 981, 840
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(622, 630) = 195930
GCD(622, 630) = ( 622 x 630 ) / 195930
= 622 / 630
= 622
Step2:
LCM(2, 981) = 1962
GCD(2, 981) = ( 2 x 981 ) / 1962
= 2 / 981
= 2
Step3:
LCM(1, 840) = 840
GCD(1, 840) = ( 1 x 840 ) / 840
= 1 / 840
= 1
So, Greatest Common Divisor of 622, 630, 981, 840 is 1
