Given numbers are 72, 84, 80, 50

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

Apply this formula for all numbers.

Step1:

LCM(72, 84) = 504

GCD(72, 84) = ( 72 x 84 ) / 504

= 72 / 84

= 72

Step2:

LCM(12, 80) = 240

GCD(12, 80) = ( 12 x 80 ) / 240

= 12 / 80

= 12

Step3:

LCM(4, 50) = 100

GCD(4, 50) = ( 4 x 50 ) / 100

= 4 / 50

= 4

So, Greatest Common Divisor of 72, 84, 80, 50 is 2
