Given numbers are 217,678,634,980,632
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 217,678,634,980,632 is 515826698520.
Find LCM of 217,678,634,980,632 with Prime Factorization
| 2 | 217, 678, 634, 980, 632 |
| 2 | 217, 339, 317, 490, 316 |
| 7 | 217, 339, 317, 245, 158 |
| 31, 339, 317, 35, 158 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 31 x 339 x 317 x 35 x 158 = 515826698520
Therefore, the lowest common multiple of 217,678,634,980,632 is 515826698520.
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.
217 x 678 x 634 x 980 x 632 = 57772590234240
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.
217 : 1, 7, 31, 217
678 : 1, 2, 3, 6, 113, 226, 339, 678
634 : 1, 2, 317, 634
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
632 : 1, 2, 4, 8, 79, 158, 316, 632
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,678,634,980,632, is 1.
Now, the common factors can be found like this.
217:7x 31
678:2x 3x 113
634:2x 317
980:2x 2x 5x 7x 7
632:2x 2x 2x 79
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 7 = 112
Therefore, the value for common factors is 112.
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 = 57772590234240/(1x112)
LCM = 57772590234240/112
LCM = 515826698520
Thus, we can understand that the LCM of 217,678,634,980,632 is 515826698520.
