Steps to Calculate GCD of 287, 281, 978, 902 using LCM Formula
Given numbers are 287, 281, 978, 902
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(287, 281) = 80647
GCD(287, 281) = ( 287 x 281 ) / 80647
= 287 / 281
= 287
Step2:
LCM(1, 978) = 978
GCD(1, 978) = ( 1 x 978 ) / 978
= 1 / 978
= 1
Step3:
LCM(1, 902) = 902
GCD(1, 902) = ( 1 x 902 ) / 902
= 1 / 902
= 1
So, Greatest Common Divisor of 287, 281, 978, 902 is 1
