Calculate the LCM of 642,476,697,276

Given numbers are 642,476,697,276

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

The LCM of 642,476,697,276 is 144086628.

Find LCM of 642,476,697,276 with Prime Factorization


2 642, 476, 697, 276
2 321, 238, 697, 138
3 321, 119, 697, 69
17 107, 119, 697, 23
107, 7, 41, 23

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

2 x 2 x 3 x 17 x 107 x 7 x 41 x 23 = 144086628

Therefore, the lowest common multiple of 642,476,697,276 is 144086628.

LCM Formula to Find Lowest Common Multiple of 642,476,697,276

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.

642 x 476 x 697 x 276 = 58787344224

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476

697 : 1, 17, 41, 697

276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,476,697,276, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

476:2x 2x 7x 17

697:17x 41

276:2x 2x 3x 23

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 3x 17 = 408

Therefore, the value for common factors is 408.

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 = 58787344224/(1x408)

LCM = 58787344224/408

LCM = 144086628

Thus, we can understand that the LCM of 642,476,697,276 is 144086628.
