Find LCM of 697,784,228,212,391 with Prime Factorization


2 697, 784, 228, 212, 391
2 697, 392, 114, 106, 391
17 697, 196, 57, 53, 391
41, 196, 57, 53, 23

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

2 x 2 x 17 x 41 x 196 x 57 x 53 x 23 = 37968846384

Therefore, the lowest common multiple of 697,784,228,212,391 is 37968846384.

LCM Formula to Find Lowest Common Multiple of 697,784,228,212,391

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.

697 x 784 x 228 x 212 x 391 = 10327526216448

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.

697 : 1, 17, 41, 697

784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784

228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228

212 : 1, 2, 4, 53, 106, 212

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,784,228,212,391, is 1.

Now, the common factors can be found like this.

697:17x 41

784:2x 2x 2x 2x 7x 7

228:2x 2x 3x 19

212:2x 2x 53

391:17x 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 2x 17 = 272

Therefore, the value for common factors is 272.

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 = 10327526216448/(1x272)

LCM = 10327526216448/272

LCM = 37968846384

Thus, we can understand that the LCM of 697,784,228,212,391 is 37968846384.
