Given numbers are 896,552,680,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 896,552,680,221 is 68315520.
Find LCM of 896,552,680,221 with Prime Factorization
| 2 | 896, 552, 680, 221 |
| 2 | 448, 276, 340, 221 |
| 2 | 224, 138, 170, 221 |
| 17 | 112, 69, 85, 221 |
| 112, 69, 5, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 17 x 112 x 69 x 5 x 13 = 68315520
Therefore, the lowest common multiple of 896,552,680,221 is 68315520.
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.
896 x 552 x 680 x 221 = 74327285760
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.
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 896,552,680,221, is 1.
Now, the common factors can be found like this.
896:2x 2x 2x 2x 2x 2x 2x 7
552:2x 2x 2x 3x 23
680:2x 2x 2x 5x 17
221:13x 17
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 2x 2x 17 = 1088
Therefore, the value for common factors is 1088.
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 = 74327285760/(1x1088)
LCM = 74327285760/1088
LCM = 68315520
Thus, we can understand that the LCM of 896,552,680,221 is 68315520.
