Given numbers are 392,620,356,252
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 392,620,356,252 is 48668760.
Find LCM of 392,620,356,252 with Prime Factorization
| 2 | 392, 620, 356, 252 |
| 2 | 196, 310, 178, 126 |
| 7 | 98, 155, 89, 63 |
| 14, 155, 89, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 14 x 155 x 89 x 9 = 48668760
Therefore, the lowest common multiple of 392,620,356,252 is 48668760.
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.
392 x 620 x 356 x 252 = 21803604480
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.
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
356 : 1, 2, 4, 89, 178, 356
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,620,356,252, is 4.
Now, the common factors can be found like this.
392:2x 2x 2x 7x 7
620:2x 2x 5x 31
356:2x 2x 89
252:2x 2x 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 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 = 21803604480/(4x112)
LCM = 21803604480/448
LCM = 48668760
Thus, we can understand that the LCM of 392,620,356,252 is 48668760.
