Steps to Calculate GCD of 775, 345, 423, 691 using LCM Formula

Given numbers are 775, 345, 423, 691

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

Apply this formula for all numbers.

Step1:

LCM(775, 345) = 53475

GCD(775, 345) = ( 775 x 345 ) / 53475

= 775 / 345

= 775


Step2:

LCM(5, 423) = 2115

GCD(5, 423) = ( 5 x 423 ) / 2115

= 5 / 423

= 5


Step3:

LCM(1, 691) = 691

GCD(1, 691) = ( 1 x 691 ) / 691

= 1 / 691

= 1


So, Greatest Common Divisor of 775, 345, 423, 691 is 1
