Given numbers are 697,409,420,872

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

The LCM of 697,409,420,872 is 26101283880.

Find LCM of 697,409,420,872 with Prime Factorization

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

2 x 2 x 697 x 409 x 105 x 218 = 26101283880

Therefore, the lowest common multiple of 697,409,420,872 is 26101283880.

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.

697 x 409 x 420 x 872 = 104405135520

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.

697 : 1, 17, 41, 697

409 : 1, 409

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

872 : 1, 2, 4, 8, 109, 218, 436, 872

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,409,420,872, is 1.

Now, the common factors can be found like this.

697:17x 41

409:409

420:2x 2x 3x 5x 7

872:2x 2x 2x 109

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 104405135520/(1x4)

LCM = 104405135520/4

LCM = 26101283880

Thus, we can understand that the LCM of 697,409,420,872 is 26101283880.
