Given numbers are 716,712,438,178,640
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 716,712,438,178,640 is 2232888960.
Find LCM of 716,712,438,178,640 with Prime Factorization
| 2 | 716, 712, 438, 178, 640 |
| 2 | 358, 356, 219, 89, 320 |
| 2 | 179, 178, 219, 89, 160 |
| 89 | 179, 89, 219, 89, 80 |
| 179, 1, 219, 1, 80 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 89 x 179 x 1 x 219 x 1 x 80 = 2232888960
Therefore, the lowest common multiple of 716,712,438,178,640 is 2232888960.
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.
716 x 712 x 438 x 178 x 640 = 25437071032320
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.
716 : 1, 2, 4, 179, 358, 716
712 : 1, 2, 4, 8, 89, 178, 356, 712
438 : 1, 2, 3, 6, 73, 146, 219, 438
178 : 1, 2, 89, 178
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 716,712,438,178,640, is 2.
Now, the common factors can be found like this.
716:2x 2x 179
712:2x 2x 2x 89
438:2x 3x 73
178:2x 89
640:2x 2x 2x 2x 2x 2x 2x 5
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 2x 2x 89 = 5696
Therefore, the value for common factors is 5696.
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 = 25437071032320/(2x5696)
LCM = 25437071032320/11392
LCM = 2232888960
Thus, we can understand that the LCM of 716,712,438,178,640 is 2232888960.
