Given numbers are 781,316,407,319
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,316,407,319 is 264812108.
Find LCM of 781,316,407,319 with Prime Factorization
| 11 | 781, 316, 407, 319 |
| 71, 316, 37, 29 |
Multiply the prime numbers at the bottom and the left side.
11 x 71 x 316 x 37 x 29 = 264812108
Therefore, the lowest common multiple of 781,316,407,319 is 264812108.
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.
781 x 316 x 407 x 319 = 32042265068
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.
781 : 1, 11, 71, 781
316 : 1, 2, 4, 79, 158, 316
407 : 1, 11, 37, 407
319 : 1, 11, 29, 319
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,316,407,319, is 1.
Now, the common factors can be found like this.
781:11x 71
316:2x 2x 79
407:11x 37
319:11x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 11 = 121
Therefore, the value for common factors is 121.
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 = 32042265068/(1x121)
LCM = 32042265068/121
LCM = 264812108
Thus, we can understand that the LCM of 781,316,407,319 is 264812108.
