Find LCM of 515,680,861,792,371 with Prime Factorization
| 2 | 515, 680, 861, 792, 371 |
| 2 | 515, 340, 861, 396, 371 |
| 2 | 515, 170, 861, 198, 371 |
| 3 | 515, 85, 861, 99, 371 |
| 5 | 515, 85, 287, 33, 371 |
| 7 | 103, 17, 287, 33, 371 |
| 103, 17, 41, 33, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 103 x 17 x 41 x 33 x 53 = 105472465560
Therefore, the lowest common multiple of 515,680,861,792,371 is 105472465560.
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.
515 x 680 x 861 x 792 x 371 = 88596871070400
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.
515 : 1, 5, 103, 515
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
861 : 1, 3, 7, 21, 41, 123, 287, 861
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
371 : 1, 7, 53, 371
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,680,861,792,371, is 1.
Now, the common factors can be found like this.
515:5x 103
680:2x 2x 2x 5x 17
861:3x 7x 41
792:2x 2x 2x 3x 3x 11
371:7x 53
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 3x 5x 7 = 840
Therefore, the value for common factors is 840.
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 = 88596871070400/(1x840)
LCM = 88596871070400/840
LCM = 105472465560
Thus, we can understand that the LCM of 515,680,861,792,371 is 105472465560.
