Steps to Calculate GCD of 713, 897, 65, 646 using LCM Formula
Given numbers are 713, 897, 65, 646
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(713, 897) = 27807
GCD(713, 897) = ( 713 x 897 ) / 27807
= 713 / 897
= 713
Step2:
LCM(23, 65) = 1495
GCD(23, 65) = ( 23 x 65 ) / 1495
= 23 / 65
= 23
Step3:
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
= 1 / 646
= 1
So, Greatest Common Divisor of 713, 897, 65, 646 is 1
