Given numbers are 642,915,190,521,937
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 642,915,190,521,937 is 1816208829030.
Find LCM of 642,915,190,521,937 with Prime Factorization
2 | 642, 915, 190, 521, 937 |
3 | 321, 915, 95, 521, 937 |
5 | 107, 305, 95, 521, 937 |
107, 61, 19, 521, 937 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 107 x 61 x 19 x 521 x 937 = 1816208829030
Therefore, the lowest common multiple of 642,915,190,521,937 is 1816208829030.
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.
642 x 915 x 190 x 521 x 937 = 54486264870900
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.
642 : 1, 2, 3, 6, 107, 214, 321, 642
915 : 1, 3, 5, 15, 61, 183, 305, 915
190 : 1, 2, 5, 10, 19, 38, 95, 190
521 : 1, 521
937 : 1, 937
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,915,190,521,937, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
915:3x 5x 61
190:2x 5x 19
521:521
937:937
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 = 54486264870900/(1x30)
LCM = 54486264870900/30
LCM = 1816208829030
Thus, we can understand that the LCM of 642,915,190,521,937 is 1816208829030.
