Calculate the LCM of 758,255,871,638

Given numbers are 758,255,871,638

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

The LCM of 758,255,871,638 is 53705433210.

Find LCM of 758,255,871,638 with Prime Factorization


2 758, 255, 871, 638
379, 255, 871, 319

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

2 x 379 x 255 x 871 x 319 = 53705433210

Therefore, the lowest common multiple of 758,255,871,638 is 53705433210.

LCM Formula to Find Lowest Common Multiple of 758,255,871,638

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.

758 x 255 x 871 x 638 = 107410866420

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.

758 : 1, 2, 379, 758

255 : 1, 3, 5, 15, 17, 51, 85, 255

871 : 1, 13, 67, 871

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 758,255,871,638, is 1.

Now, the common factors can be found like this.

758:2x 379

255:3x 5x 17

871:13x 67

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.

2 = 2

Therefore, the value for common factors is 2.

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 = 107410866420/(1x2)

LCM = 107410866420/2

LCM = 53705433210

Thus, we can understand that the LCM of 758,255,871,638 is 53705433210.
