Given numbers are 438,434,936,881,686

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

The LCM of 438,434,936,881,686 is 640074360744.

Find LCM of 438,434,936,881,686 with Prime Factorization

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

2 x 3 x 7 x 73 x 31 x 156 x 881 x 49 = 640074360744

Therefore, the lowest common multiple of 438,434,936,881,686 is 640074360744.

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.

438 x 434 x 936 x 881 x 686 = 107532492604992

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.

438 : 1, 2, 3, 6, 73, 146, 219, 438

434 : 1, 2, 7, 14, 31, 62, 217, 434

936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936

881 : 1, 881

686 : 1, 2, 7, 14, 49, 98, 343, 686

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,434,936,881,686, is 1.

Now, the common factors can be found like this.

438:2x 3x 73

434:2x 7x 31

936:2x 2x 2x 3x 3x 13

881:881

686:2x 7x 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 3x 7 = 168

Therefore, the value for common factors is 168.

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 = 107532492604992/(1x168)

LCM = 107532492604992/168

LCM = 640074360744

Thus, we can understand that the LCM of 438,434,936,881,686 is 640074360744.
