The LCM of 644,245,248,588 is 4192440.

Find LCM of 644,245,248,588 with Prime Factorization


2 644, 245, 248, 588
2 322, 245, 124, 294
7 161, 245, 62, 147
7 23, 35, 62, 21
23, 5, 62, 3

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

2 x 2 x 7 x 7 x 23 x 5 x 62 x 3 = 4192440

Therefore, the lowest common multiple of 644,245,248,588 is 4192440.

LCM Formula to Find Lowest Common Multiple of 644,245,248,588

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.

644 x 245 x 248 x 588 = 23008110720

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.

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

245 : 1, 5, 7, 35, 49, 245

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

588 : 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 49, 84, 98, 147, 196, 294, 588

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,245,248,588, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

245:5x 7x 7

248:2x 2x 2x 31

588:2x 2x 3x 7x 7

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 2x 2x 7x 7x 7 = 5488

Therefore, the value for common factors is 5488.

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 = 23008110720/(1x5488)

LCM = 23008110720/5488

LCM = 4192440

Thus, we can understand that the LCM of 644,245,248,588 is 4192440.
