Given numbers are 561, 858, 509, 907

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

Apply this formula for all numbers.

Step1:

LCM(561, 858) = 14586

GCD(561, 858) = ( 561 x 858 ) / 14586

= 561 / 858

= 561

Step2:

LCM(33, 509) = 16797

GCD(33, 509) = ( 33 x 509 ) / 16797

= 33 / 509

= 33

Step3:

LCM(1, 907) = 907

GCD(1, 907) = ( 1 x 907 ) / 907

= 1 / 907

= 1

So, Greatest Common Divisor of 561, 858, 509, 907 is 1
