Steps to Calculate GCD of 878, 198, 985, 280 using LCM Formula

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
