Find LCM of 784,347,639,136,273 with Prime Factorization
| 2 | 784, 347, 639, 136, 273 |
| 2 | 392, 347, 639, 68, 273 |
| 2 | 196, 347, 639, 34, 273 |
| 3 | 98, 347, 639, 17, 273 |
| 7 | 98, 347, 213, 17, 91 |
| 14, 347, 213, 17, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 14 x 347 x 213 x 17 x 13 = 38418346512
Therefore, the lowest common multiple of 784,347,639,136,273 is 38418346512.
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.
784 x 347 x 639 x 136 x 273 = 6454282214016
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
347 : 1, 347
639 : 1, 3, 9, 71, 213, 639
136 : 1, 2, 4, 8, 17, 34, 68, 136
273 : 1, 3, 7, 13, 21, 39, 91, 273
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,347,639,136,273, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
347:347
639:3x 3x 71
136:2x 2x 2x 17
273:3x 7x 13
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 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 6454282214016/(1x168)
LCM = 6454282214016/168
LCM = 38418346512
Thus, we can understand that the LCM of 784,347,639,136,273 is 38418346512.
