Given numbers are 655, 245, 824, 523

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

Apply this formula for all numbers.

Step1:

LCM(655, 245) = 32095

GCD(655, 245) = ( 655 x 245 ) / 32095

= 655 / 245

= 655

Step2:

LCM(5, 824) = 4120

GCD(5, 824) = ( 5 x 824 ) / 4120

= 5 / 824

= 5

Step3:

LCM(1, 523) = 523

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

= 1 / 523

= 1

So, Greatest Common Divisor of 655, 245, 824, 523 is 1
