Find LCM of 770,948,649,319,985 with Prime Factorization
| 2 | 770, 948, 649, 319, 985 |
| 5 | 385, 474, 649, 319, 985 |
| 11 | 77, 474, 649, 319, 197 |
| 7, 474, 59, 29, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 7 x 474 x 59 x 29 x 197 = 123022713660
Therefore, the lowest common multiple of 770,948,649,319,985 is 123022713660.
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.
770 x 948 x 649 x 319 x 985 = 148857483528600
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.
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
948 : 1, 2, 3, 4, 6, 12, 79, 158, 237, 316, 474, 948
649 : 1, 11, 59, 649
319 : 1, 11, 29, 319
985 : 1, 5, 197, 985
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,948,649,319,985, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
948:2x 2x 3x 79
649:11x 59
319:11x 29
985:5x 197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 11x 11 = 1210
Therefore, the value for common factors is 1210.
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 = 148857483528600/(1x1210)
LCM = 148857483528600/1210
LCM = 123022713660
Thus, we can understand that the LCM of 770,948,649,319,985 is 123022713660.
