Given numbers are 140,691,735,670,750
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 140,691,735,670,750 is 3402829500.
Find LCM of 140,691,735,670,750 with Prime Factorization
| 2 | 140, 691, 735, 670, 750 |
| 3 | 70, 691, 735, 335, 375 |
| 5 | 70, 691, 245, 335, 125 |
| 7 | 14, 691, 49, 67, 25 |
| 2, 691, 7, 67, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 2 x 691 x 7 x 67 x 25 = 3402829500
Therefore, the lowest common multiple of 140,691,735,670,750 is 3402829500.
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.
140 x 691 x 735 x 670 x 750 = 35729709750000
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.
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
691 : 1, 691
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
670 : 1, 2, 5, 10, 67, 134, 335, 670
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 140,691,735,670,750, is 1.
Now, the common factors can be found like this.
140:2x 2x 5x 7
691:691
735:3x 5x 7x 7
670:2x 5x 67
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 2x 3x 5x 5x 5x 7 = 10500
Therefore, the value for common factors is 10500.
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 = 35729709750000/(1x10500)
LCM = 35729709750000/10500
LCM = 3402829500
Thus, we can understand that the LCM of 140,691,735,670,750 is 3402829500.
