Given numbers are 781,578,334,143
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,578,334,143 is 980028478.
Find LCM of 781,578,334,143 with Prime Factorization
2 | 781, 578, 334, 143 |
11 | 781, 289, 167, 143 |
71, 289, 167, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 71 x 289 x 167 x 13 = 980028478
Therefore, the lowest common multiple of 781,578,334,143 is 980028478.
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.
781 x 578 x 334 x 143 = 21560626516
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.
781 : 1, 11, 71, 781
578 : 1, 2, 17, 34, 289, 578
334 : 1, 2, 167, 334
143 : 1, 11, 13, 143
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,578,334,143, is 1.
Now, the common factors can be found like this.
781:11x 71
578:2x 17x 17
334:2x 167
143:11x 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 11 = 22
Therefore, the value for common factors is 22.
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 = 21560626516/(1x22)
LCM = 21560626516/22
LCM = 980028478
Thus, we can understand that the LCM of 781,578,334,143 is 980028478.
