Steps to Calculate GCD of 805, 115, 642, 731 using LCM Formula
Given numbers are 805, 115, 642, 731
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(805, 115) = 805
GCD(805, 115) = ( 805 x 115 ) / 805
= 805 / 115
= 805
Step2:
LCM(115, 642) = 73830
GCD(115, 642) = ( 115 x 642 ) / 73830
= 115 / 642
= 115
Step3:
LCM(1, 731) = 731
GCD(1, 731) = ( 1 x 731 ) / 731
= 1 / 731
= 1
So, Greatest Common Divisor of 805, 115, 642, 731 is 1
