Given numbers are 642,665,267,117,750
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 642,665,267,117,750 is 37046850750.
Find LCM of 642,665,267,117,750 with Prime Factorization
| 2 | 642, 665, 267, 117, 750 |
| 3 | 321, 665, 267, 117, 375 |
| 5 | 107, 665, 89, 39, 125 |
| 107, 133, 89, 39, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 107 x 133 x 89 x 39 x 25 = 37046850750
Therefore, the lowest common multiple of 642,665,267,117,750 is 37046850750.
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.
642 x 665 x 267 x 117 x 750 = 10002649702500
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.
642 : 1, 2, 3, 6, 107, 214, 321, 642
665 : 1, 5, 7, 19, 35, 95, 133, 665
267 : 1, 3, 89, 267
117 : 1, 3, 9, 13, 39, 117
750 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 125, 150, 250, 375, 750
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,665,267,117,750, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
665:5x 7x 19
267:3x 89
117:3x 3x 13
750:2x 3x 5x 5x 5
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 3x 3x 5 = 270
Therefore, the value for common factors is 270.
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 = 10002649702500/(1x270)
LCM = 10002649702500/270
LCM = 37046850750
Thus, we can understand that the LCM of 642,665,267,117,750 is 37046850750.
