Find LCM of 658,391,686,153,402 with Prime Factorization


2 658, 391, 686, 153, 402
3 329, 391, 343, 153, 201
7 329, 391, 343, 51, 67
17 47, 391, 49, 51, 67
47, 23, 49, 3, 67

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

2 x 3 x 7 x 17 x 47 x 23 x 49 x 3 x 67 = 7601793066

Therefore, the lowest common multiple of 658,391,686,153,402 is 7601793066.

LCM Formula to Find Lowest Common Multiple of 658,391,686,153,402

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.

658 x 391 x 686 x 153 x 402 = 10855360498248

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.

658 : 1, 2, 7, 14, 47, 94, 329, 658

391 : 1, 17, 23, 391

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

153 : 1, 3, 9, 17, 51, 153

402 : 1, 2, 3, 6, 67, 134, 201, 402

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 658,391,686,153,402, is 1.

Now, the common factors can be found like this.

658:2x 7x 47

391:17x 23

686:2x 7x 7x 7

153:3x 3x 17

402:2x 3x 67

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 7x 17 = 1428

Therefore, the value for common factors is 1428.

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 = 10855360498248/(1x1428)

LCM = 10855360498248/1428

LCM = 7601793066

Thus, we can understand that the LCM of 658,391,686,153,402 is 7601793066.
