Given numbers are 624,700,870,356
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 624,700,870,356 is 281845200.
Find LCM of 624,700,870,356 with Prime Factorization
| 2 | 624, 700, 870, 356 |
| 2 | 312, 350, 435, 178 |
| 3 | 156, 175, 435, 89 |
| 5 | 52, 175, 145, 89 |
| 52, 35, 29, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 52 x 35 x 29 x 89 = 281845200
Therefore, the lowest common multiple of 624,700,870,356 is 281845200.
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.
624 x 700 x 870 x 356 = 135285696000
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.
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
356 : 1, 2, 4, 89, 178, 356
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 624,700,870,356, is 2.
Now, the common factors can be found like this.
624:2x 2x 2x 2x 3x 13
700:2x 2x 5x 5x 7
870:2x 3x 5x 29
356:2x 2x 89
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 3x 5 = 240
Therefore, the value for common factors is 240.
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 = 135285696000/(2x240)
LCM = 135285696000/480
LCM = 281845200
Thus, we can understand that the LCM of 624,700,870,356 is 281845200.
