Steps to Calculate GCD of 780, 398, 288, 369 using LCM Formula

Given numbers are 780, 398, 288, 369

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

Apply this formula for all numbers.

Step1:

LCM(780, 398) = 155220

GCD(780, 398) = ( 780 x 398 ) / 155220

= 780 / 398

= 780


Step2:

LCM(2, 288) = 288

GCD(2, 288) = ( 2 x 288 ) / 288

= 2 / 288

= 2


Step3:

LCM(2, 369) = 738

GCD(2, 369) = ( 2 x 369 ) / 738

= 2 / 369

= 2


So, Greatest Common Divisor of 780, 398, 288, 369 is 1
