Given numbers are 292,390,518,769,791
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 292,390,518,769,791 is 1281510031620.
Find LCM of 292,390,518,769,791 with Prime Factorization
| 2 | 292, 390, 518, 769, 791 |
| 7 | 146, 195, 259, 769, 791 |
| 146, 195, 37, 769, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 146 x 195 x 37 x 769 x 113 = 1281510031620
Therefore, the lowest common multiple of 292,390,518,769,791 is 1281510031620.
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.
292 x 390 x 518 x 769 x 791 = 35882280885360
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.
292 : 1, 2, 4, 73, 146, 292
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
518 : 1, 2, 7, 14, 37, 74, 259, 518
769 : 1, 769
791 : 1, 7, 113, 791
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 292,390,518,769,791, is 1.
Now, the common factors can be found like this.
292:2x 2x 73
390:2x 3x 5x 13
518:2x 7x 37
769:769
791:7x 113
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 = 35882280885360/(1x28)
LCM = 35882280885360/28
LCM = 1281510031620
Thus, we can understand that the LCM of 292,390,518,769,791 is 1281510031620.
