Given numbers are 290, 716, 47, 821

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

Apply this formula for all numbers.

Step1:

LCM(290, 716) = 103820

GCD(290, 716) = ( 290 x 716 ) / 103820

= 290 / 716

= 290

Step2:

LCM(2, 47) = 94

GCD(2, 47) = ( 2 x 47 ) / 94

= 2 / 47

= 2

Step3:

LCM(1, 821) = 821

GCD(1, 821) = ( 1 x 821 ) / 821

= 1 / 821

= 1

So, Greatest Common Divisor of 290, 716, 47, 821 is 1
