Given numbers are 616, 581, 821, 165

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

Apply this formula for all numbers.

Step1:

LCM(616, 581) = 51128

GCD(616, 581) = ( 616 x 581 ) / 51128

= 616 / 581

= 616

Step2:

LCM(7, 821) = 5747

GCD(7, 821) = ( 7 x 821 ) / 5747

= 7 / 821

= 7

Step3:

LCM(1, 165) = 165

GCD(1, 165) = ( 1 x 165 ) / 165

= 1 / 165

= 1

So, Greatest Common Divisor of 616, 581, 821, 165 is 1
