Given numbers are 415, 153, 245, 641

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

Apply this formula for all numbers.

Step1:

LCM(415, 153) = 63495

GCD(415, 153) = ( 415 x 153 ) / 63495

= 415 / 153

= 415

Step2:

LCM(1, 245) = 245

GCD(1, 245) = ( 1 x 245 ) / 245

= 1 / 245

= 1

Step3:

LCM(1, 641) = 641

GCD(1, 641) = ( 1 x 641 ) / 641

= 1 / 641

= 1

So, Greatest Common Divisor of 415, 153, 245, 641 is 1
