Find LCM of 888,690,654,545,820 with Prime Factorization
| 2 | 888, 690, 654, 545, 820 |
| 2 | 444, 345, 327, 545, 410 |
| 3 | 222, 345, 327, 545, 205 |
| 5 | 74, 115, 109, 545, 205 |
| 109 | 74, 23, 109, 109, 41 |
| 74, 23, 1, 1, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 109 x 74 x 23 x 1 x 1 x 41 = 456374280
Therefore, the lowest common multiple of 888,690,654,545,820 is 456374280.
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.
888 x 690 x 654 x 545 x 820 = 179081267472000
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.
888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
654 : 1, 2, 3, 6, 109, 218, 327, 654
545 : 1, 5, 109, 545
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 888,690,654,545,820, is 1.
Now, the common factors can be found like this.
888:2x 2x 2x 3x 37
690:2x 3x 5x 23
654:2x 3x 109
545:5x 109
820:2x 2x 5x 41
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 3x 3x 5x 5x 109 = 392400
Therefore, the value for common factors is 392400.
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 = 179081267472000/(1x392400)
LCM = 179081267472000/392400
LCM = 456374280
Thus, we can understand that the LCM of 888,690,654,545,820 is 456374280.
