Given numbers are 785,968,824,492
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 785,968,824,492 is 9626919720.
Find LCM of 785,968,824,492 with Prime Factorization
| 2 | 785, 968, 824, 492 |
| 2 | 785, 484, 412, 246 |
| 2 | 785, 242, 206, 123 |
| 785, 121, 103, 123 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 785 x 121 x 103 x 123 = 9626919720
Therefore, the lowest common multiple of 785,968,824,492 is 9626919720.
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.
785 x 968 x 824 x 492 = 308061431040
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.
785 : 1, 5, 157, 785
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
824 : 1, 2, 4, 8, 103, 206, 412, 824
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,968,824,492, is 1.
Now, the common factors can be found like this.
785:5x 157
968:2x 2x 2x 11x 11
824:2x 2x 2x 103
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 2 = 32
Therefore, the value for common factors is 32.
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 = 308061431040/(1x32)
LCM = 308061431040/32
LCM = 9626919720
Thus, we can understand that the LCM of 785,968,824,492 is 9626919720.
