Given numbers are 70, 36, 14, 90

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

Apply this formula for all numbers.

**Step1:**

LCM(70, 36) = 1260

GCD(70, 36) = ( 70 x 36 ) / 1260

= 70 / 36

= 70

**Step2:**

LCM(2, 14) = 14

GCD(2, 14) = ( 2 x 14 ) / 14

= 2 / 14

= 2

**Step3:**

LCM(2, 90) = 90

GCD(2, 90) = ( 2 x 90 ) / 90

= 2 / 90

= 2
