LCM Formula to Find Lowest Common Multiple of 476,316,918,234,642

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.

476 x 316 x 918 x 234 x 642 = 20743765870464

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.

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

316 : 1, 2, 4, 79, 158, 316

918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918

234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 476,316,918,234,642, is 2.

Now, the common factors can be found like this.

476:2x 2x 7x 17

316:2x 2x 79

918:2x 3x 3x 3x 17

234:2x 3x 3x 13

642:2x 3x 107

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 3x 3x 3x 17 = 7344

Therefore, the value for common factors is 7344.

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 = 20743765870464/(2x7344)

LCM = 20743765870464/14688

LCM = 1412293428

Thus, we can understand that the LCM of 476,316,918,234,642 is 1412293428.
