Given numbers are 690, 618, 451, 806
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 618) = 71070
GCD(690, 618) = ( 690 x 618 ) / 71070
= 690 / 618
= 690
Step2:
LCM(6, 451) = 2706
GCD(6, 451) = ( 6 x 451 ) / 2706
= 6 / 451
= 6
Step3:
LCM(1, 806) = 806
GCD(1, 806) = ( 1 x 806 ) / 806
= 1 / 806
= 1
So, Greatest Common Divisor of 690, 618, 451, 806 is 1
