Given numbers are 829,974,785,392,378
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 829,974,785,392,378 is 3354308322120.
Find LCM of 829,974,785,392,378 with Prime Factorization
| 2 | 829, 974, 785, 392, 378 |
| 7 | 829, 487, 785, 196, 189 |
| 829, 487, 785, 28, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 829 x 487 x 785 x 28 x 27 = 3354308322120
Therefore, the lowest common multiple of 829,974,785,392,378 is 3354308322120.
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.
829 x 974 x 785 x 392 x 378 = 93920633019360
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.
829 : 1, 829
974 : 1, 2, 487, 974
785 : 1, 5, 157, 785
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 829,974,785,392,378, is 1.
Now, the common factors can be found like this.
829:829
974:2x 487
785:5x 157
392:2x 2x 2x 7x 7
378:2x 3x 3x 3x 7
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 7 = 28
Therefore, the value for common factors is 28.
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 = 93920633019360/(1x28)
LCM = 93920633019360/28
LCM = 3354308322120
Thus, we can understand that the LCM of 829,974,785,392,378 is 3354308322120.
