Steps to Calculate GCD of 287, 148, 155, 133 using LCM Formula

Given numbers are 287, 148, 155, 133

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

Apply this formula for all numbers.

Step1:

LCM(287, 148) = 42476

GCD(287, 148) = ( 287 x 148 ) / 42476

= 287 / 148

= 287


Step2:

LCM(1, 155) = 155

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

= 1 / 155

= 1


Step3:

LCM(1, 133) = 133

GCD(1, 133) = ( 1 x 133 ) / 133

= 1 / 133

= 1


So, Greatest Common Divisor of 287, 148, 155, 133 is 1
