Given numbers are 876, 980, 978, 815
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(876, 980) = 214620
GCD(876, 980) = ( 876 x 980 ) / 214620
= 876 / 980
= 876
Step2:
LCM(4, 978) = 1956
GCD(4, 978) = ( 4 x 978 ) / 1956
= 4 / 978
= 4
Step3:
LCM(2, 815) = 1630
GCD(2, 815) = ( 2 x 815 ) / 1630
= 2 / 815
= 2
So, Greatest Common Divisor of 876, 980, 978, 815 is 1
