Given numbers are 785,551,455,865,655
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 785,551,455,865,655 is 892031204155.
Find LCM of 785,551,455,865,655 with Prime Factorization
| 5 | 785, 551, 455, 865, 655 |
| 157, 551, 91, 173, 131 |
Multiply the prime numbers at the bottom and the left side.
5 x 157 x 551 x 91 x 173 x 131 = 892031204155
Therefore, the lowest common multiple of 785,551,455,865,655 is 892031204155.
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 551 x 455 x 865 x 655 = 111503900519375
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
551 : 1, 19, 29, 551
455 : 1, 5, 7, 13, 35, 65, 91, 455
865 : 1, 5, 173, 865
655 : 1, 5, 131, 655
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,551,455,865,655, is 1.
Now, the common factors can be found like this.
785:5x 157
551:19x 29
455:5x 7x 13
865:5x 173
655:5x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 5 = 125
Therefore, the value for common factors is 125.
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 = 111503900519375/(1x125)
LCM = 111503900519375/125
LCM = 892031204155
Thus, we can understand that the LCM of 785,551,455,865,655 is 892031204155.
