Given numbers are 290, 620, 743, 806
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(290, 620) = 17980
GCD(290, 620) = ( 290 x 620 ) / 17980
= 290 / 620
= 290
Step2:
LCM(10, 743) = 7430
GCD(10, 743) = ( 10 x 743 ) / 7430
= 10 / 743
= 10
Step3:
LCM(1, 806) = 806
GCD(1, 806) = ( 1 x 806 ) / 806
= 1 / 806
= 1
So, Greatest Common Divisor of 290, 620, 743, 806 is 1
