Steps to Calculate GCD of 1, 30, 69 using LCM Formula

Given numbers are 1, 30, 69

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

Apply this formula for all numbers.

Step1:

LCM(1, 30) = 30

GCD(1, 30) = ( 1 x 30 ) / 30

= 1 / 30

= 1


Step2:

LCM(1, 69) = 69

GCD(1, 69) = ( 1 x 69 ) / 69

= 1 / 69

= 1


So, Greatest Common Divisor of 1, 30, 69 is 1
