Steps to Calculate GCD of 842, 821, 346, 905 using LCM Formula

Given numbers are 842, 821, 346, 905

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

Apply this formula for all numbers.

Step1:

LCM(842, 821) = 691282

GCD(842, 821) = ( 842 x 821 ) / 691282

= 842 / 821

= 842


Step2:

LCM(1, 346) = 346

GCD(1, 346) = ( 1 x 346 ) / 346

= 1 / 346

= 1


Step3:

LCM(1, 905) = 905

GCD(1, 905) = ( 1 x 905 ) / 905

= 1 / 905

= 1


So, Greatest Common Divisor of 842, 821, 346, 905 is 1
