Given numbers are 441,931,697,680,281
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 441,931,697,680,281 is 65643432120.
Find LCM of 441,931,697,680,281 with Prime Factorization
| 7 | 441, 931, 697, 680, 281 |
| 7 | 63, 133, 697, 680, 281 |
| 17 | 9, 19, 697, 680, 281 |
| 9, 19, 41, 40, 281 |
Multiply the prime numbers at the bottom and the left side.
7 x 7 x 17 x 9 x 19 x 41 x 40 x 281 = 65643432120
Therefore, the lowest common multiple of 441,931,697,680,281 is 65643432120.
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.
441 x 931 x 697 x 680 x 281 = 54680978955960
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.
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
931 : 1, 7, 19, 49, 133, 931
697 : 1, 17, 41, 697
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
281 : 1, 281
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 441,931,697,680,281, is 1.
Now, the common factors can be found like this.
441:3x 3x 7x 7
931:7x 7x 19
697:17x 41
680:2x 2x 2x 5x 17
281:281
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 7x 17 = 833
Therefore, the value for common factors is 833.
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 = 54680978955960/(1x833)
LCM = 54680978955960/833
LCM = 65643432120
Thus, we can understand that the LCM of 441,931,697,680,281 is 65643432120.
