The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 980, 812, 258, 643
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(980, 812) = 28420
GCD(980, 812) = ( 980 x 812 ) / 28420
= 980 / 812
= 980
Step2:
LCM(28, 258) = 3612
GCD(28, 258) = ( 28 x 258 ) / 3612
= 28 / 258
= 28
Step3:
LCM(2, 643) = 1286
GCD(2, 643) = ( 2 x 643 ) / 1286
= 2 / 643
= 2
So, Greatest Common Divisor of 980, 812, 258, 643 is 1
