Given numbers are 980, 422, 311, 144
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(980, 422) = 206780
GCD(980, 422) = ( 980 x 422 ) / 206780
= 980 / 422
= 980
Step2:
LCM(2, 311) = 622
GCD(2, 311) = ( 2 x 311 ) / 622
= 2 / 311
= 2
Step3:
LCM(1, 144) = 144
GCD(1, 144) = ( 1 x 144 ) / 144
= 1 / 144
= 1
So, Greatest Common Divisor of 980, 422, 311, 144 is 1
