Given numbers are 358,756,368,140
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 358,756,368,140 is 62249040.
Find LCM of 358,756,368,140 with Prime Factorization
| 2 | 358, 756, 368, 140 |
| 2 | 179, 378, 184, 70 |
| 7 | 179, 189, 92, 35 |
| 179, 27, 92, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 179 x 27 x 92 x 5 = 62249040
Therefore, the lowest common multiple of 358,756,368,140 is 62249040.
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.
358 x 756 x 368 x 140 = 13943784960
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.
358 : 1, 2, 179, 358
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 358,756,368,140, is 2.
Now, the common factors can be found like this.
358:2x 179
756:2x 2x 3x 3x 3x 7
368:2x 2x 2x 2x 23
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.
2x 2x 2x 2x 7 = 112
Therefore, the value for common factors is 112.
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 = 13943784960/(2x112)
LCM = 13943784960/224
LCM = 62249040
Thus, we can understand that the LCM of 358,756,368,140 is 62249040.
