Find LCM of 438,974,655,205,786 with Prime Factorization


2 438, 974, 655, 205, 786
3 219, 487, 655, 205, 393
5 73, 487, 655, 205, 131
131 73, 487, 131, 41, 131
73, 487, 1, 41, 1

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

2 x 3 x 5 x 131 x 73 x 487 x 1 x 41 x 1 = 5728332630

Therefore, the lowest common multiple of 438,974,655,205,786 is 5728332630.

LCM Formula to Find Lowest Common Multiple of 438,974,655,205,786

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 974 x 655 x 205 x 786 = 45024694471800

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

974 : 1, 2, 487, 974

655 : 1, 5, 131, 655

205 : 1, 5, 41, 205

786 : 1, 2, 3, 6, 131, 262, 393, 786

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,974,655,205,786, is 1.

Now, the common factors can be found like this.

438:2x 3x 73

974:2x 487

655:5x 131

205:5x 41

786:2x 3x 131

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 3x 5x 131 = 7860

Therefore, the value for common factors is 7860.

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 = 45024694471800/(1x7860)

LCM = 45024694471800/7860

LCM = 5728332630

Thus, we can understand that the LCM of 438,974,655,205,786 is 5728332630.
