Given numbers are 698,748,646,789

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

The LCM of 698,748,646,789 is 3913430532.

Find LCM of 698,748,646,789 with Prime Factorization

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

2 x 17 x 349 x 22 x 19 x 789 = 3913430532

Therefore, the lowest common multiple of 698,748,646,789 is 3913430532.

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.

698 x 748 x 646 x 789 = 266113276176

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.

698 : 1, 2, 349, 698

748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748

646 : 1, 2, 17, 19, 34, 38, 323, 646

789 : 1, 3, 263, 789

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 698,748,646,789, is 1.

Now, the common factors can be found like this.

698:2x 349

748:2x 2x 11x 17

646:2x 17x 19

789:3x 263

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

2x 2x 17 = 68

Therefore, the value for common factors is 68.

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 = 266113276176/(1x68)

LCM = 266113276176/68

LCM = 3913430532

Thus, we can understand that the LCM of 698,748,646,789 is 3913430532.
