Given numbers are 154, 820, 281, 523

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

Apply this formula for all numbers.

Step1:

LCM(154, 820) = 63140

GCD(154, 820) = ( 154 x 820 ) / 63140

= 154 / 820

= 154

Step2:

LCM(2, 281) = 562

GCD(2, 281) = ( 2 x 281 ) / 562

= 2 / 281

= 2

Step3:

LCM(1, 523) = 523

GCD(1, 523) = ( 1 x 523 ) / 523

= 1 / 523

= 1

So, Greatest Common Divisor of 154, 820, 281, 523 is 1
