Given numbers are 747, 387, 153, 380

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

Apply this formula for all numbers.

Step1:

LCM(747, 387) = 32121

GCD(747, 387) = ( 747 x 387 ) / 32121

= 747 / 387

= 747

Step2:

LCM(9, 153) = 153

GCD(9, 153) = ( 9 x 153 ) / 153

= 9 / 153

= 9

Step3:

LCM(9, 380) = 3420

GCD(9, 380) = ( 9 x 380 ) / 3420

= 9 / 380

= 9

So, Greatest Common Divisor of 747, 387, 153, 380 is 1
