Given numbers are 378,784,706,754,628
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 378,784,706,754,628 is 442278201456.
Find LCM of 378,784,706,754,628 with Prime Factorization
| 2 | 378, 784, 706, 754, 628 |
| 2 | 189, 392, 353, 377, 314 |
| 7 | 189, 196, 353, 377, 157 |
| 27, 28, 353, 377, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 27 x 28 x 353 x 377 x 157 = 442278201456
Therefore, the lowest common multiple of 378,784,706,754,628 is 442278201456.
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.
378 x 784 x 706 x 754 x 628 = 99070317126144
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.
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
706 : 1, 2, 353, 706
754 : 1, 2, 13, 26, 29, 58, 377, 754
628 : 1, 2, 4, 157, 314, 628
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 378,784,706,754,628, is 2.
Now, the common factors can be found like this.
378:2x 3x 3x 3x 7
784:2x 2x 2x 2x 7x 7
706:2x 353
754:2x 13x 29
628:2x 2x 157
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 7 = 112
Therefore, the value for common factors is 112.
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 = 99070317126144/(2x112)
LCM = 99070317126144/224
LCM = 442278201456
Thus, we can understand that the LCM of 378,784,706,754,628 is 442278201456.
