Steps to Calculate GCD of 743, 285, 861, 805 using LCM Formula
Given numbers are 743, 285, 861, 805
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(743, 285) = 211755
GCD(743, 285) = ( 743 x 285 ) / 211755
= 743 / 285
= 743
Step2:
LCM(1, 861) = 861
GCD(1, 861) = ( 1 x 861 ) / 861
= 1 / 861
= 1
Step3:
LCM(1, 805) = 805
GCD(1, 805) = ( 1 x 805 ) / 805
= 1 / 805
= 1
So, Greatest Common Divisor of 743, 285, 861, 805 is 1
