Given numbers are 989,456,935,980,100
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 989,456,935,980,100 is 103309159800.
Find LCM of 989,456,935,980,100 with Prime Factorization
| 2 | 989, 456, 935, 980, 100 |
| 2 | 989, 228, 935, 490, 50 |
| 5 | 989, 114, 935, 245, 25 |
| 989, 114, 187, 49, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 989 x 114 x 187 x 49 x 5 = 103309159800
Therefore, the lowest common multiple of 989,456,935,980,100 is 103309159800.
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.
989 x 456 x 935 x 980 x 100 = 41323663920000
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.
989 : 1, 23, 43, 989
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
935 : 1, 5, 11, 17, 55, 85, 187, 935
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,456,935,980,100, is 1.
Now, the common factors can be found like this.
989:23x 43
456:2x 2x 2x 3x 19
935:5x 11x 17
980:2x 2x 5x 7x 7
100:2x 2x 5x 5
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 5x 5 = 400
Therefore, the value for common factors is 400.
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 = 41323663920000/(1x400)
LCM = 41323663920000/400
LCM = 103309159800
Thus, we can understand that the LCM of 989,456,935,980,100 is 103309159800.
