Steps to Calculate GCD of 153, 391, 785, 731 using LCM Formula
Given numbers are 153, 391, 785, 731
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(153, 391) = 3519
GCD(153, 391) = ( 153 x 391 ) / 3519
= 153 / 391
= 153
Step2:
LCM(17, 785) = 13345
GCD(17, 785) = ( 17 x 785 ) / 13345
= 17 / 785
= 17
Step3:
LCM(1, 731) = 731
GCD(1, 731) = ( 1 x 731 ) / 731
= 1 / 731
= 1
So, Greatest Common Divisor of 153, 391, 785, 731 is 1
