Given numbers are 917,533,168,628
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 917,533,168,628 is 1841651448.
Find LCM of 917,533,168,628 with Prime Factorization
| 2 | 917, 533, 168, 628 |
| 2 | 917, 533, 84, 314 |
| 7 | 917, 533, 42, 157 |
| 131, 533, 6, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 131 x 533 x 6 x 157 = 1841651448
Therefore, the lowest common multiple of 917,533,168,628 is 1841651448.
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.
917 x 533 x 168 x 628 = 51566240544
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.
917 : 1, 7, 131, 917
533 : 1, 13, 41, 533
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
628 : 1, 2, 4, 157, 314, 628
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 917,533,168,628, is 1.
Now, the common factors can be found like this.
917:7x 131
533:13x 41
168:2x 2x 2x 3x 7
628:2x 2x 157
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 7 = 28
Therefore, the value for common factors is 28.
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 = 51566240544/(1x28)
LCM = 51566240544/28
LCM = 1841651448
Thus, we can understand that the LCM of 917,533,168,628 is 1841651448.
