Given numbers are 940,529,392,28
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 940,529,392,28 is 48731480.
Find LCM of 940,529,392,28 with Prime Factorization
| 2 | 940, 529, 392, 28 |
| 2 | 470, 529, 196, 14 |
| 7 | 235, 529, 98, 7 |
| 235, 529, 14, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 235 x 529 x 14 x 1 = 48731480
Therefore, the lowest common multiple of 940,529,392,28 is 48731480.
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.
940 x 529 x 392 x 28 = 5457925760
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.
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
529 : 1, 23, 529
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
28 : 1, 2, 4, 7, 14, 28
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 940,529,392,28, is 1.
Now, the common factors can be found like this.
940:2x 2x 5x 47
529:23x 23
392:2x 2x 2x 7x 7
28:2x 2x 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 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 = 5457925760/(1x112)
LCM = 5457925760/112
LCM = 48731480
Thus, we can understand that the LCM of 940,529,392,28 is 48731480.
