Given numbers are 142, 196, 622, 255
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(142, 196) = 13916
GCD(142, 196) = ( 142 x 196 ) / 13916
= 142 / 196
= 142
Step2:
LCM(2, 622) = 622
GCD(2, 622) = ( 2 x 622 ) / 622
= 2 / 622
= 2
Step3:
LCM(2, 255) = 510
GCD(2, 255) = ( 2 x 255 ) / 510
= 2 / 255
= 2
So, Greatest Common Divisor of 142, 196, 622, 255 is 1
