Given numbers are 917,497,641,247,136
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 917,497,641,247,136 is 1401914654504.
Find LCM of 917,497,641,247,136 with Prime Factorization
| 7 | 917, 497, 641, 247, 136 |
| 131, 71, 641, 247, 136 |
Multiply the prime numbers at the bottom and the left side.
7 x 131 x 71 x 641 x 247 x 136 = 1401914654504
Therefore, the lowest common multiple of 917,497,641,247,136 is 1401914654504.
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.
917 x 497 x 641 x 247 x 136 = 9813402581528
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.
917 : 1, 7, 131, 917
497 : 1, 7, 71, 497
641 : 1, 641
247 : 1, 13, 19, 247
136 : 1, 2, 4, 8, 17, 34, 68, 136
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 917,497,641,247,136, is 1.
Now, the common factors can be found like this.
917:7x 131
497:7x 71
641:641
247:13x 19
136:2x 2x 2x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 9813402581528/(1x7)
LCM = 9813402581528/7
LCM = 1401914654504
Thus, we can understand that the LCM of 917,497,641,247,136 is 1401914654504.
