GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(862, 120) = 51720
GCD(862, 120) = ( 862 x 120 ) / 51720
= 862 / 120
= 862
Step2:
LCM(2, 122) = 122
GCD(2, 122) = ( 2 x 122 ) / 122
= 2 / 122
= 2
Step3:
LCM(2, 478) = 478
GCD(2, 478) = ( 2 x 478 ) / 478
= 2 / 478
= 2
So, Greatest Common Divisor of 862, 120, 122, 478 is 2
