Given numbers are 380, 138, 325, 653

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

Apply this formula for all numbers.

Step1:

LCM(380, 138) = 26220

GCD(380, 138) = ( 380 x 138 ) / 26220

= 380 / 138

= 380

Step2:

LCM(2, 325) = 650

GCD(2, 325) = ( 2 x 325 ) / 650

= 2 / 325

= 2

Step3:

LCM(1, 653) = 653

GCD(1, 653) = ( 1 x 653 ) / 653

= 1 / 653

= 1

So, Greatest Common Divisor of 380, 138, 325, 653 is 1
