Given numbers are 770, 343, 85, 803

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

Apply this formula for all numbers.

Step1:

LCM(770, 343) = 37730

GCD(770, 343) = ( 770 x 343 ) / 37730

= 770 / 343

= 770

Step2:

LCM(7, 85) = 595

GCD(7, 85) = ( 7 x 85 ) / 595

= 7 / 85

= 7

Step3:

LCM(1, 803) = 803

GCD(1, 803) = ( 1 x 803 ) / 803

= 1 / 803

= 1

So, Greatest Common Divisor of 770, 343, 85, 803 is 1
