Given numbers are 561,437,391,776

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

The LCM of 561,437,391,776 is 190241832.

Find LCM of 561,437,391,776 with Prime Factorization

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

17 x 23 x 33 x 19 x 1 x 776 = 190241832

Therefore, the lowest common multiple of 561,437,391,776 is 190241832.

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.

561 x 437 x 391 x 776 = 74384556312

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.

561 : 1, 3, 11, 17, 33, 51, 187, 561

437 : 1, 19, 23, 437

391 : 1, 17, 23, 391

776 : 1, 2, 4, 8, 97, 194, 388, 776

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,437,391,776, is 1.

Now, the common factors can be found like this.

561:3x 11x 17

437:19x 23

391:17x 23

776:2x 2x 2x 97

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

17x 23 = 391

Therefore, the value for common factors is 391.

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 = 74384556312/(1x391)

LCM = 74384556312/391

LCM = 190241832

Thus, we can understand that the LCM of 561,437,391,776 is 190241832.
