Given numbers are 419,931,768,153,628
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 419,931,768,153,628 is 2398803934464.
Find LCM of 419,931,768,153,628 with Prime Factorization
| 2 | 419, 931, 768, 153, 628 |
| 2 | 419, 931, 384, 153, 314 |
| 3 | 419, 931, 192, 153, 157 |
| 419, 931, 64, 51, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 419 x 931 x 64 x 51 x 157 = 2398803934464
Therefore, the lowest common multiple of 419,931,768,153,628 is 2398803934464.
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.
419 x 931 x 768 x 153 x 628 = 28785647213568
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.
419 : 1, 419
931 : 1, 7, 19, 49, 133, 931
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
153 : 1, 3, 9, 17, 51, 153
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 419,931,768,153,628, is 1.
Now, the common factors can be found like this.
419:419
931:7x 7x 19
768:2x 2x 2x 2x 2x 2x 2x 2x 3
153:3x 3x 17
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 3 = 12
Therefore, the value for common factors is 12.
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 = 28785647213568/(1x12)
LCM = 28785647213568/12
LCM = 2398803934464
Thus, we can understand that the LCM of 419,931,768,153,628 is 2398803934464.
