Given numbers are 838,742,763,248

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

The LCM of 838,742,763,248 is 4202097368.

Find LCM of 838,742,763,248 with Prime Factorization

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

2 x 7 x 419 x 53 x 109 x 124 = 4202097368

Therefore, the lowest common multiple of 838,742,763,248 is 4202097368.

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.

838 x 742 x 763 x 248 = 117658726304

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.

838 : 1, 2, 419, 838

742 : 1, 2, 7, 14, 53, 106, 371, 742

763 : 1, 7, 109, 763

248 : 1, 2, 4, 8, 31, 62, 124, 248

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,742,763,248, is 1.

Now, the common factors can be found like this.

838:2x 419

742:2x 7x 53

763:7x 109

248:2x 2x 2x 31

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 7 = 28

Therefore, the value for common factors is 28.

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 = 117658726304/(1x28)

LCM = 117658726304/28

LCM = 4202097368

Thus, we can understand that the LCM of 838,742,763,248 is 4202097368.
