Given numbers are 397,782,749,674

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 397,782,749,674 is 78362625502.

Find LCM of 397,782,749,674 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 397 x 391 x 749 x 337 = 78362625502

Therefore, the lowest common multiple of 397,782,749,674 is 78362625502.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

397 x 782 x 749 x 674 = 156725251004

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

397 : 1, 397

782 : 1, 2, 17, 23, 34, 46, 391, 782

749 : 1, 7, 107, 749

674 : 1, 2, 337, 674

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,782,749,674, is 1.

Now, the common factors can be found like this.

397:397

782:2x 17x 23

749:7x 107

674:2x 337

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 156725251004/(1x2)

LCM = 156725251004/2

LCM = 78362625502

Thus, we can understand that the LCM of 397,782,749,674 is 78362625502.
