Given numbers are 245, 680, 802, 977

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

Apply this formula for all numbers.

Step1:

LCM(245, 680) = 33320

GCD(245, 680) = ( 245 x 680 ) / 33320

= 245 / 680

= 245

Step2:

LCM(5, 802) = 4010

GCD(5, 802) = ( 5 x 802 ) / 4010

= 5 / 802

= 5

Step3:

LCM(1, 977) = 977

GCD(1, 977) = ( 1 x 977 ) / 977

= 1 / 977

= 1

So, Greatest Common Divisor of 245, 680, 802, 977 is 1
