Given numbers are 190,909,820,707
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 190,909,820,707 is 99135540.
Find LCM of 190,909,820,707 with Prime Factorization
| 2 | 190, 909, 820, 707 |
| 5 | 95, 909, 410, 707 |
| 101 | 19, 909, 82, 707 |
| 19, 9, 82, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 101 x 19 x 9 x 82 x 7 = 99135540
Therefore, the lowest common multiple of 190,909,820,707 is 99135540.
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.
190 x 909 x 820 x 707 = 100126895400
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.
190 : 1, 2, 5, 10, 19, 38, 95, 190
909 : 1, 3, 9, 101, 303, 909
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
707 : 1, 7, 101, 707
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 190,909,820,707, is 1.
Now, the common factors can be found like this.
190:2x 5x 19
909:3x 3x 101
820:2x 2x 5x 41
707:7x 101
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 101 = 1010
Therefore, the value for common factors is 1010.
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 = 100126895400/(1x1010)
LCM = 100126895400/1010
LCM = 99135540
Thus, we can understand that the LCM of 190,909,820,707 is 99135540.
