Given numbers are 438,101,803,391

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

The LCM of 438,101,803,391 is 190267638.

Find LCM of 438,101,803,391 with Prime Factorization

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

73 x 6 x 101 x 11 x 391 = 190267638

Therefore, the lowest common multiple of 438,101,803,391 is 190267638.

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.

438 x 101 x 803 x 391 = 13889537574

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.

438 : 1, 2, 3, 6, 73, 146, 219, 438

101 : 1, 101

803 : 1, 11, 73, 803

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,101,803,391, is 1.

Now, the common factors can be found like this.

438:2x 3x 73

101:101

803:11x 73

391:17x 23

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

73 = 73

Therefore, the value for common factors is 73.

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 = 13889537574/(1x73)

LCM = 13889537574/73

LCM = 190267638

Thus, we can understand that the LCM of 438,101,803,391 is 190267638.
