Given numbers are 371,148,689,638

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

The LCM of 371,148,689,638 is 227703476.

Find LCM of 371,148,689,638 with Prime Factorization

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

2 x 53 x 7 x 74 x 13 x 319 = 227703476

Therefore, the lowest common multiple of 371,148,689,638 is 227703476.

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.

371 x 148 x 689 x 638 = 24136568456

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.

371 : 1, 7, 53, 371

148 : 1, 2, 4, 37, 74, 148

689 : 1, 13, 53, 689

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 371,148,689,638, is 1.

Now, the common factors can be found like this.

371:7x 53

148:2x 2x 37

689:13x 53

638:2x 11x 29

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

2x 53 = 106

Therefore, the value for common factors is 106.

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 = 24136568456/(1x106)

LCM = 24136568456/106

LCM = 227703476

Thus, we can understand that the LCM of 371,148,689,638 is 227703476.
