Given numbers are 980, 478, 912, 991
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(980, 478) = 234220
GCD(980, 478) = ( 980 x 478 ) / 234220
= 980 / 478
= 980
Step2:
LCM(2, 912) = 912
GCD(2, 912) = ( 2 x 912 ) / 912
= 2 / 912
= 2
Step3:
LCM(2, 991) = 1982
GCD(2, 991) = ( 2 x 991 ) / 1982
= 2 / 991
= 2
So, Greatest Common Divisor of 980, 478, 912, 991 is 1
