Given numbers are 901,550,980,665,789
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 901,550,980,665,789 is 728021424900.
Find LCM of 901,550,980,665,789 with Prime Factorization
| 2 | 901, 550, 980, 665, 789 |
| 5 | 901, 275, 490, 665, 789 |
| 7 | 901, 55, 98, 133, 789 |
| 901, 55, 14, 19, 789 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 901 x 55 x 14 x 19 x 789 = 728021424900
Therefore, the lowest common multiple of 901,550,980,665,789 is 728021424900.
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.
901 x 550 x 980 x 665 x 789 = 254807498715000
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.
901 : 1, 17, 53, 901
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
665 : 1, 5, 7, 19, 35, 95, 133, 665
789 : 1, 3, 263, 789
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 901,550,980,665,789, is 1.
Now, the common factors can be found like this.
901:17x 53
550:2x 5x 5x 11
980:2x 2x 5x 7x 7
665:5x 7x 19
789:3x 263
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 7 = 350
Therefore, the value for common factors is 350.
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 = 254807498715000/(1x350)
LCM = 254807498715000/350
LCM = 728021424900
Thus, we can understand that the LCM of 901,550,980,665,789 is 728021424900.
