Given numbers are 428,216,766,764,492
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 428,216,766,764,492 is 69319197576.
Find LCM of 428,216,766,764,492 with Prime Factorization
| 2 | 428, 216, 766, 764, 492 |
| 2 | 214, 108, 383, 382, 246 |
| 3 | 107, 54, 383, 191, 123 |
| 107, 18, 383, 191, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 107 x 18 x 383 x 191 x 41 = 69319197576
Therefore, the lowest common multiple of 428,216,766,764,492 is 69319197576.
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.
428 x 216 x 766 x 764 x 492 = 26618571869184
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.
428 : 1, 2, 4, 107, 214, 428
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
766 : 1, 2, 383, 766
764 : 1, 2, 4, 191, 382, 764
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,216,766,764,492, is 2.
Now, the common factors can be found like this.
428:2x 2x 107
216:2x 2x 2x 3x 3x 3
766:2x 383
764:2x 2x 191
492:2x 2x 3x 41
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 2x 2x 2x 2x 3 = 192
Therefore, the value for common factors is 192.
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 = 26618571869184/(2x192)
LCM = 26618571869184/384
LCM = 69319197576
Thus, we can understand that the LCM of 428,216,766,764,492 is 69319197576.
