Given numbers are 245, 665, 953, 784

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

Apply this formula for all numbers.

Step1:

LCM(245, 665) = 4655

GCD(245, 665) = ( 245 x 665 ) / 4655

= 245 / 665

= 245

Step2:

LCM(35, 953) = 33355

GCD(35, 953) = ( 35 x 953 ) / 33355

= 35 / 953

= 35

Step3:

LCM(1, 784) = 784

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

= 1 / 784

= 1

So, Greatest Common Divisor of 245, 665, 953, 784 is 1
