Given numbers are 641, 678, 830, 290

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

Apply this formula for all numbers.

Step1:

LCM(641, 678) = 434598

GCD(641, 678) = ( 641 x 678 ) / 434598

= 641 / 678

= 641

Step2:

LCM(1, 830) = 830

GCD(1, 830) = ( 1 x 830 ) / 830

= 1 / 830

= 1

Step3:

LCM(1, 290) = 290

GCD(1, 290) = ( 1 x 290 ) / 290

= 1 / 290

= 1

So, Greatest Common Divisor of 641, 678, 830, 290 is 1
