Given numbers are 705, 415, 147, 189

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

Apply this formula for all numbers.

Step1:

LCM(705, 415) = 58515

GCD(705, 415) = ( 705 x 415 ) / 58515

= 705 / 415

= 705

Step2:

LCM(5, 147) = 735

GCD(5, 147) = ( 5 x 147 ) / 735

= 5 / 147

= 5

Step3:

LCM(1, 189) = 189

GCD(1, 189) = ( 1 x 189 ) / 189

= 1 / 189

= 1

So, Greatest Common Divisor of 705, 415, 147, 189 is 1
