Given numbers are 878, 280, 831, 245
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(878, 280) = 122920
GCD(878, 280) = ( 878 x 280 ) / 122920
= 878 / 280
= 878
Step2:
LCM(2, 831) = 1662
GCD(2, 831) = ( 2 x 831 ) / 1662
= 2 / 831
= 2
Step3:
LCM(1, 245) = 245
GCD(1, 245) = ( 1 x 245 ) / 245
= 1 / 245
= 1
So, Greatest Common Divisor of 878, 280, 831, 245 is 1
