Given numbers are 980, 807, 771, 897
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(980, 807) = 790860
GCD(980, 807) = ( 980 x 807 ) / 790860
= 980 / 807
= 980
Step2:
LCM(1, 771) = 771
GCD(1, 771) = ( 1 x 771 ) / 771
= 1 / 771
= 1
Step3:
LCM(1, 897) = 897
GCD(1, 897) = ( 1 x 897 ) / 897
= 1 / 897
= 1
So, Greatest Common Divisor of 980, 807, 771, 897 is 1
