Given numbers are 54, 84, 20, 62

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

Apply this formula for all numbers.

Step1:

LCM(54, 84) = 756

GCD(54, 84) = ( 54 x 84 ) / 756

= 54 / 84

= 54

Step2:

LCM(6, 20) = 60

GCD(6, 20) = ( 6 x 20 ) / 60

= 6 / 20

= 6

Step3:

LCM(2, 62) = 62

GCD(2, 62) = ( 2 x 62 ) / 62

= 2 / 62

= 2

So, Greatest Common Divisor of 54, 84, 20, 62 is 2
