Given numbers are 841, 103, 86, 646

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

Apply this formula for all numbers.

Step1:

LCM(841, 103) = 86623

GCD(841, 103) = ( 841 x 103 ) / 86623

= 841 / 103

= 841

Step2:

LCM(1, 86) = 86

GCD(1, 86) = ( 1 x 86 ) / 86

= 1 / 86

= 1

Step3:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

So, Greatest Common Divisor of 841, 103, 86, 646 is 1
