Given numbers are 577,702,949,978
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 577,702,949,978 is 4819737546.
Find LCM of 577,702,949,978 with Prime Factorization
| 2 | 577, 702, 949, 978 |
| 3 | 577, 351, 949, 489 |
| 13 | 577, 117, 949, 163 |
| 577, 9, 73, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 577 x 9 x 73 x 163 = 4819737546
Therefore, the lowest common multiple of 577,702,949,978 is 4819737546.
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.
577 x 702 x 949 x 978 = 375939528588
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.
577 : 1, 577
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
949 : 1, 13, 73, 949
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 577,702,949,978, is 1.
Now, the common factors can be found like this.
577:577
702:2x 3x 3x 3x 13
949:13x 73
978:2x 3x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 13 = 78
Therefore, the value for common factors is 78.
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 = 375939528588/(1x78)
LCM = 375939528588/78
LCM = 4819737546
Thus, we can understand that the LCM of 577,702,949,978 is 4819737546.
