Given numbers are 253, 715, 636, 381

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

Apply this formula for all numbers.

Step1:

LCM(253, 715) = 16445

GCD(253, 715) = ( 253 x 715 ) / 16445

= 253 / 715

= 253

Step2:

LCM(11, 636) = 6996

GCD(11, 636) = ( 11 x 636 ) / 6996

= 11 / 636

= 11

Step3:

LCM(1, 381) = 381

GCD(1, 381) = ( 1 x 381 ) / 381

= 1 / 381

= 1

So, Greatest Common Divisor of 253, 715, 636, 381 is 1
