Given numbers are 620, 821, 158

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

Apply this formula for all numbers.

Step1:

LCM(620, 821) = 509020

GCD(620, 821) = ( 620 x 821 ) / 509020

= 620 / 821

= 620

Step2:

LCM(1, 158) = 158

GCD(1, 158) = ( 1 x 158 ) / 158

= 1 / 158

= 1

So, Greatest Common Divisor of 620, 821, 158 is 1
