Given numbers are 45, 87, 19

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

Apply this formula for all numbers.

Step1:

LCM(45, 87) = 1305

GCD(45, 87) = ( 45 x 87 ) / 1305

= 45 / 87

= 45

Step2:

LCM(3, 19) = 57

GCD(3, 19) = ( 3 x 19 ) / 57

= 3 / 19

= 3

So, Greatest Common Divisor of 45, 87, 19 is 1
