Given numbers are 215, 645, 157, 327

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

Apply this formula for all numbers.

Step1:

LCM(215, 645) = 645

GCD(215, 645) = ( 215 x 645 ) / 645

= 215 / 645

= 215

Step2:

LCM(215, 157) = 33755

GCD(215, 157) = ( 215 x 157 ) / 33755

= 215 / 157

= 215

Step3:

LCM(1, 327) = 327

GCD(1, 327) = ( 1 x 327 ) / 327

= 1 / 327

= 1

So, Greatest Common Divisor of 215, 645, 157, 327 is 1
