Steps to Calculate GCD of 378, 857, 729, 800 using LCM Formula

Given numbers are 378, 857, 729, 800

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

Apply this formula for all numbers.

Step1:

LCM(378, 857) = 323946

GCD(378, 857) = ( 378 x 857 ) / 323946

= 378 / 857

= 378


Step2:

LCM(1, 729) = 729

GCD(1, 729) = ( 1 x 729 ) / 729

= 1 / 729

= 1


Step3:

LCM(1, 800) = 800

GCD(1, 800) = ( 1 x 800 ) / 800

= 1 / 800

= 1


So, Greatest Common Divisor of 378, 857, 729, 800 is 1
