Given numbers are 581, 609, 791, 156

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

Apply this formula for all numbers.

Step1:

LCM(581, 609) = 50547

GCD(581, 609) = ( 581 x 609 ) / 50547

= 581 / 609

= 581

Step2:

LCM(7, 791) = 791

GCD(7, 791) = ( 7 x 791 ) / 791

= 7 / 791

= 7

Step3:

LCM(7, 156) = 1092

GCD(7, 156) = ( 7 x 156 ) / 1092

= 7 / 156

= 7

So, Greatest Common Divisor of 581, 609, 791, 156 is 1
