The LCM of 289,488,670,428 is 5055292040.

Find LCM of 289,488,670,428 with Prime Factorization


2 289, 488, 670, 428
2 289, 244, 335, 214
289, 122, 335, 107

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

2 x 2 x 289 x 122 x 335 x 107 = 5055292040

Therefore, the lowest common multiple of 289,488,670,428 is 5055292040.

LCM Formula to Find Lowest Common Multiple of 289,488,670,428

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.

289 x 488 x 670 x 428 = 40442336320

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.

289 : 1, 17, 289

488 : 1, 2, 4, 8, 61, 122, 244, 488

670 : 1, 2, 5, 10, 67, 134, 335, 670

428 : 1, 2, 4, 107, 214, 428

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 289,488,670,428, is 1.

Now, the common factors can be found like this.

289:17x 17

488:2x 2x 2x 61

670:2x 5x 67

428:2x 2x 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 2 = 8

Therefore, the value for common factors is 8.

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 = 40442336320/(1x8)

LCM = 40442336320/8

LCM = 5055292040

Thus, we can understand that the LCM of 289,488,670,428 is 5055292040.
