Given numbers are 921, 280, 784, 969

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

Apply this formula for all numbers.

Step1:

LCM(921, 280) = 257880

GCD(921, 280) = ( 921 x 280 ) / 257880

= 921 / 280

= 921

Step2:

LCM(1, 784) = 784

GCD(1, 784) = ( 1 x 784 ) / 784

= 1 / 784

= 1

Step3:

LCM(1, 969) = 969

GCD(1, 969) = ( 1 x 969 ) / 969

= 1 / 969

= 1

So, Greatest Common Divisor of 921, 280, 784, 969 is 1
