Given numbers are 265,175,742,280
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 265,175,742,280 is 74200.
Find LCM of 265,175,742,280 with Prime Factorization
| 2 | 265, 175, 742, 280 |
| 5 | 265, 175, 371, 140 |
| 7 | 53, 35, 371, 28 |
| 53 | 53, 5, 53, 4 |
| 1, 5, 1, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 53 x 1 x 5 x 1 x 4 = 74200
Therefore, the lowest common multiple of 265,175,742,280 is 74200.
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.
265 x 175 x 742 x 280 = 9634870000
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.
265 : 1, 5, 53, 265
175 : 1, 5, 7, 25, 35, 175
742 : 1, 2, 7, 14, 53, 106, 371, 742
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 265,175,742,280, is 1.
Now, the common factors can be found like this.
265:5x 53
175:5x 5x 7
742:2x 7x 53
280:2x 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.
2x 5x 5x 7x 7x 53 = 129850
Therefore, the value for common factors is 129850.
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 = 9634870000/(1x129850)
LCM = 9634870000/129850
LCM = 74200
Thus, we can understand that the LCM of 265,175,742,280 is 74200.
