Given numbers are 813, 963, 780, 887
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(813, 963) = 260973
GCD(813, 963) = ( 813 x 963 ) / 260973
= 813 / 963
= 813
Step2:
LCM(3, 780) = 780
GCD(3, 780) = ( 3 x 780 ) / 780
= 3 / 780
= 3
Step3:
LCM(3, 887) = 2661
GCD(3, 887) = ( 3 x 887 ) / 2661
= 3 / 887
= 3
So, Greatest Common Divisor of 813, 963, 780, 887 is 1
