Given numbers are 878, 198, 985, 280
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(878, 198) = 86922
GCD(878, 198) = ( 878 x 198 ) / 86922
= 878 / 198
= 878
Step2:
LCM(2, 985) = 1970
GCD(2, 985) = ( 2 x 985 ) / 1970
= 2 / 985
= 2
Step3:
LCM(1, 280) = 280
GCD(1, 280) = ( 1 x 280 ) / 280
= 1 / 280
= 1
So, Greatest Common Divisor of 878, 198, 985, 280 is 1
