Given numbers are 245,151,755,140
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 245,151,755,140 is 147980.
Find LCM of 245,151,755,140 with Prime Factorization
| 5 | 245, 151, 755, 140 |
| 7 | 49, 151, 151, 28 |
| 151 | 7, 151, 151, 4 |
| 7, 1, 1, 4 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 151 x 7 x 1 x 1 x 4 = 147980
Therefore, the lowest common multiple of 245,151,755,140 is 147980.
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.
245 x 151 x 755 x 140 = 3910371500
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.
245 : 1, 5, 7, 35, 49, 245
151 : 1, 151
755 : 1, 5, 151, 755
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 245,151,755,140, is 1.
Now, the common factors can be found like this.
245:5x 7x 7
151:151
755:5x 151
140:2x 2x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 7x 151 = 26425
Therefore, the value for common factors is 26425.
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 = 3910371500/(1x26425)
LCM = 3910371500/26425
LCM = 147980
Thus, we can understand that the LCM of 245,151,755,140 is 147980.
