Given numbers are 742,416,177,578
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 742,416,177,578 is 7894749408.
Find LCM of 742,416,177,578 with Prime Factorization
| 2 | 742, 416, 177, 578 |
| 371, 208, 177, 289 |
Multiply the prime numbers at the bottom and the left side.
2 x 371 x 208 x 177 x 289 = 7894749408
Therefore, the lowest common multiple of 742,416,177,578 is 7894749408.
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.
742 x 416 x 177 x 578 = 31578997632
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.
742 : 1, 2, 7, 14, 53, 106, 371, 742
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
177 : 1, 3, 59, 177
578 : 1, 2, 17, 34, 289, 578
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,416,177,578, is 1.
Now, the common factors can be found like this.
742:2x 7x 53
416:2x 2x 2x 2x 2x 13
177:3x 59
578:2x 17x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 31578997632/(1x4)
LCM = 31578997632/4
LCM = 7894749408
Thus, we can understand that the LCM of 742,416,177,578 is 7894749408.
