Given numbers are 969, 747, 45, 784

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

Apply this formula for all numbers.

Step1:

LCM(969, 747) = 241281

GCD(969, 747) = ( 969 x 747 ) / 241281

= 969 / 747

= 969

Step2:

LCM(3, 45) = 45

GCD(3, 45) = ( 3 x 45 ) / 45

= 3 / 45

= 3

Step3:

LCM(3, 784) = 2352

GCD(3, 784) = ( 3 x 784 ) / 2352

= 3 / 784

= 3

So, Greatest Common Divisor of 969, 747, 45, 784 is 1
