Steps to Calculate GCD of 258, 345, 139, 615 using LCM Formula
Given numbers are 258, 345, 139, 615
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(258, 345) = 29670
GCD(258, 345) = ( 258 x 345 ) / 29670
= 258 / 345
= 258
Step2:
LCM(3, 139) = 417
GCD(3, 139) = ( 3 x 139 ) / 417
= 3 / 139
= 3
Step3:
LCM(1, 615) = 615
GCD(1, 615) = ( 1 x 615 ) / 615
= 1 / 615
= 1
So, Greatest Common Divisor of 258, 345, 139, 615 is 1
