Steps to Calculate GCD of 986, 217, 155, 430 using LCM Formula

Given numbers are 986, 217, 155, 430

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(986, 217) = 213962

GCD(986, 217) = ( 986 x 217 ) / 213962

= 986 / 217

= 986


Step2:

LCM(1, 155) = 155

GCD(1, 155) = ( 1 x 155 ) / 155

= 1 / 155

= 1


Step3:

LCM(1, 430) = 430

GCD(1, 430) = ( 1 x 430 ) / 430

= 1 / 430

= 1


So, Greatest Common Divisor of 986, 217, 155, 430 is 1
