Given numbers are 980, 112, 129, 770
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(980, 112) = 3920
GCD(980, 112) = ( 980 x 112 ) / 3920
= 980 / 112
= 980
Step2:
LCM(28, 129) = 3612
GCD(28, 129) = ( 28 x 129 ) / 3612
= 28 / 129
= 28
Step3:
LCM(1, 770) = 770
GCD(1, 770) = ( 1 x 770 ) / 770
= 1 / 770
= 1
So, Greatest Common Divisor of 980, 112, 129, 770 is 1
