Steps to Calculate GCD of 805, 647, 34, 508 using LCM Formula

Given numbers are 805, 647, 34, 508

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(805, 647) = 520835

GCD(805, 647) = ( 805 x 647 ) / 520835

= 805 / 647

= 805


Step2:

LCM(1, 34) = 34

GCD(1, 34) = ( 1 x 34 ) / 34

= 1 / 34

= 1


Step3:

LCM(1, 508) = 508

GCD(1, 508) = ( 1 x 508 ) / 508

= 1 / 508

= 1


So, Greatest Common Divisor of 805, 647, 34, 508 is 1
