Steps to Calculate GCD of 70, 30, 50, 82 using LCM Formula

Given numbers are 70, 30, 50, 82

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

Apply this formula for all numbers.

Step1:

LCM(70, 30) = 210

GCD(70, 30) = ( 70 x 30 ) / 210

= 70 / 30

= 70


Step2:

LCM(10, 50) = 50

GCD(10, 50) = ( 10 x 50 ) / 50

= 10 / 50

= 10


Step3:

LCM(10, 82) = 410

GCD(10, 82) = ( 10 x 82 ) / 410

= 10 / 82

= 10


So, Greatest Common Divisor of 70, 30, 50, 82 is 2
