Given numbers are 220, 400, 342, 122
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(220, 400) = 4400
GCD(220, 400) = ( 220 x 400 ) / 4400
= 220 / 400
= 220
Step2:
LCM(20, 342) = 3420
GCD(20, 342) = ( 20 x 342 ) / 3420
= 20 / 342
= 20
Step3:
LCM(2, 122) = 122
GCD(2, 122) = ( 2 x 122 ) / 122
= 2 / 122
= 2
So, Greatest Common Divisor of 220, 400, 342, 122 is 2
