Given numbers are 138, 826, 163, 561

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

Apply this formula for all numbers.

Step1:

LCM(138, 826) = 56994

GCD(138, 826) = ( 138 x 826 ) / 56994

= 138 / 826

= 138

Step2:

LCM(2, 163) = 326

GCD(2, 163) = ( 2 x 163 ) / 326

= 2 / 163

= 2

Step3:

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

= 1 / 561

= 1

So, Greatest Common Divisor of 138, 826, 163, 561 is 1
