Steps to Calculate GCD of 728, 407, 398, 841 using LCM Formula

Given numbers are 728, 407, 398, 841

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

Apply this formula for all numbers.

Step1:

LCM(728, 407) = 296296

GCD(728, 407) = ( 728 x 407 ) / 296296

= 728 / 407

= 728


Step2:

LCM(1, 398) = 398

GCD(1, 398) = ( 1 x 398 ) / 398

= 1 / 398

= 1


Step3:

LCM(1, 841) = 841

GCD(1, 841) = ( 1 x 841 ) / 841

= 1 / 841

= 1


So, Greatest Common Divisor of 728, 407, 398, 841 is 1
