Given numbers are 761,374,480,860,287
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 761,374,480,860,287 is 842981129760.
Find LCM of 761,374,480,860,287 with Prime Factorization
| 2 | 761, 374, 480, 860, 287 |
| 2 | 761, 187, 240, 430, 287 |
| 5 | 761, 187, 120, 215, 287 |
| 761, 187, 24, 43, 287 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 761 x 187 x 24 x 43 x 287 = 842981129760
Therefore, the lowest common multiple of 761,374,480,860,287 is 842981129760.
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.
761 x 374 x 480 x 860 x 287 = 33719245190400
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.
761 : 1, 761
374 : 1, 2, 11, 17, 22, 34, 187, 374
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
287 : 1, 7, 41, 287
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 761,374,480,860,287, is 1.
Now, the common factors can be found like this.
761:761
374:2x 11x 17
480:2x 2x 2x 2x 2x 3x 5
860:2x 2x 5x 43
287:7x 41
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 5 = 40
Therefore, the value for common factors is 40.
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 = 33719245190400/(1x40)
LCM = 33719245190400/40
LCM = 842981129760
Thus, we can understand that the LCM of 761,374,480,860,287 is 842981129760.
