Given numbers are 882,991,905,780
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 882,991,905,780 is 20566678860.
Find LCM of 882,991,905,780 with Prime Factorization
| 2 | 882, 991, 905, 780 |
| 3 | 441, 991, 905, 390 |
| 5 | 147, 991, 905, 130 |
| 147, 991, 181, 26 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 147 x 991 x 181 x 26 = 20566678860
Therefore, the lowest common multiple of 882,991,905,780 is 20566678860.
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.
882 x 991 x 905 x 780 = 617000365800
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.
882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882
991 : 1, 991
905 : 1, 5, 181, 905
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 882,991,905,780, is 1.
Now, the common factors can be found like this.
882:2x 3x 3x 7x 7
991:991
905:5x 181
780:2x 2x 3x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5 = 30
Therefore, the value for common factors is 30.
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 = 617000365800/(1x30)
LCM = 617000365800/30
LCM = 20566678860
Thus, we can understand that the LCM of 882,991,905,780 is 20566678860.
