Given numbers are 974,520,193,817,731
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 974,520,193,817,731 is 678829319480.
Find LCM of 974,520,193,817,731 with Prime Factorization
2 | 974, 520, 193, 817, 731 |
43 | 487, 260, 193, 817, 731 |
487, 260, 193, 19, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 43 x 487 x 260 x 193 x 19 x 17 = 678829319480
Therefore, the lowest common multiple of 974,520,193,817,731 is 678829319480.
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.
974 x 520 x 193 x 817 x 731 = 58379321475280
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.
974 : 1, 2, 487, 974
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
193 : 1, 193
817 : 1, 19, 43, 817
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 974,520,193,817,731, is 1.
Now, the common factors can be found like this.
974:2x 487
520:2x 2x 2x 5x 13
193:193
817:19x 43
731:17x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 43 = 86
Therefore, the value for common factors is 86.
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 = 58379321475280/(1x86)
LCM = 58379321475280/86
LCM = 678829319480
Thus, we can understand that the LCM of 974,520,193,817,731 is 678829319480.
