Given numbers are 4,974,672,392
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 4,974,672,392 is 2290848.
Find LCM of 4,974,672,392 with Prime Factorization
| 2 | 4, 974, 672, 392 |
| 2 | 2, 487, 336, 196 |
| 2 | 1, 487, 168, 98 |
| 7 | 1, 487, 84, 49 |
| 1, 487, 12, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 1 x 487 x 12 x 7 = 2290848
Therefore, the lowest common multiple of 4,974,672,392 is 2290848.
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.
4 x 974 x 672 x 392 = 1026299904
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.
4 : 1, 2, 4
974 : 1, 2, 487, 974
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 4,974,672,392, is 2.
Now, the common factors can be found like this.
4:2x 2
974:2x 487
672:2x 2x 2x 2x 2x 3x 7
392:2x 2x 2x 7x 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 2x 7 = 224
Therefore, the value for common factors is 224.
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 = 1026299904/(2x224)
LCM = 1026299904/448
LCM = 2290848
Thus, we can understand that the LCM of 4,974,672,392 is 2290848.
