Steps to Calculate GCD of 691, 428, 15, 707 using LCM Formula
Given numbers are 691, 428, 15, 707
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(691, 428) = 295748
GCD(691, 428) = ( 691 x 428 ) / 295748
= 691 / 428
= 691
Step2:
LCM(1, 15) = 15
GCD(1, 15) = ( 1 x 15 ) / 15
= 1 / 15
= 1
Step3:
LCM(1, 707) = 707
GCD(1, 707) = ( 1 x 707 ) / 707
= 1 / 707
= 1
So, Greatest Common Divisor of 691, 428, 15, 707 is 1
