Given numbers are 634,153,436,238,680
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 634,153,436,238,680 is 1480250520.
Find LCM of 634,153,436,238,680 with Prime Factorization
| 2 | 634, 153, 436, 238, 680 |
| 2 | 317, 153, 218, 119, 340 |
| 17 | 317, 153, 109, 119, 170 |
| 317, 9, 109, 7, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 317 x 9 x 109 x 7 x 10 = 1480250520
Therefore, the lowest common multiple of 634,153,436,238,680 is 1480250520.
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.
634 x 153 x 436 x 238 x 680 = 6844678404480
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.
634 : 1, 2, 317, 634
153 : 1, 3, 9, 17, 51, 153
436 : 1, 2, 4, 109, 218, 436
238 : 1, 2, 7, 14, 17, 34, 119, 238
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 634,153,436,238,680, is 1.
Now, the common factors can be found like this.
634:2x 317
153:3x 3x 17
436:2x 2x 109
238:2x 7x 17
680:2x 2x 2x 5x 17
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 17x 17 = 4624
Therefore, the value for common factors is 4624.
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 = 6844678404480/(1x4624)
LCM = 6844678404480/4624
LCM = 1480250520
Thus, we can understand that the LCM of 634,153,436,238,680 is 1480250520.
