Steps to Calculate GCD of 115, 355, 278, 989 using LCM Formula
Given numbers are 115, 355, 278, 989
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(115, 355) = 8165
GCD(115, 355) = ( 115 x 355 ) / 8165
= 115 / 355
= 115
Step2:
LCM(5, 278) = 1390
GCD(5, 278) = ( 5 x 278 ) / 1390
= 5 / 278
= 5
Step3:
LCM(1, 989) = 989
GCD(1, 989) = ( 1 x 989 ) / 989
= 1 / 989
= 1
So, Greatest Common Divisor of 115, 355, 278, 989 is 1
