Given numbers are 455, 525, 655, 871

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

Apply this formula for all numbers.

Step1:

LCM(455, 525) = 6825

GCD(455, 525) = ( 455 x 525 ) / 6825

= 455 / 525

= 455

Step2:

LCM(35, 655) = 4585

GCD(35, 655) = ( 35 x 655 ) / 4585

= 35 / 655

= 35

Step3:

LCM(5, 871) = 4355

GCD(5, 871) = ( 5 x 871 ) / 4355

= 5 / 871

= 5

So, Greatest Common Divisor of 455, 525, 655, 871 is 1
