Given numbers are 665, 287, 181, 253

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

Apply this formula for all numbers.

Step1:

LCM(665, 287) = 27265

GCD(665, 287) = ( 665 x 287 ) / 27265

= 665 / 287

= 665

Step2:

LCM(7, 181) = 1267

GCD(7, 181) = ( 7 x 181 ) / 1267

= 7 / 181

= 7

Step3:

LCM(1, 253) = 253

GCD(1, 253) = ( 1 x 253 ) / 253

= 1 / 253

= 1

So, Greatest Common Divisor of 665, 287, 181, 253 is 1
