Given numbers are 980, 865, 503, 868
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(980, 865) = 169540
GCD(980, 865) = ( 980 x 865 ) / 169540
= 980 / 865
= 980
Step2:
LCM(5, 503) = 2515
GCD(5, 503) = ( 5 x 503 ) / 2515
= 5 / 503
= 5
Step3:
LCM(1, 868) = 868
GCD(1, 868) = ( 1 x 868 ) / 868
= 1 / 868
= 1
So, Greatest Common Divisor of 980, 865, 503, 868 is 1
