Given numbers are 787,186,620,620
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 787,186,620,620 is 1463820.
Find LCM of 787,186,620,620 with Prime Factorization
2 | 787, 186, 620, 620 |
2 | 787, 93, 310, 310 |
5 | 787, 93, 155, 155 |
31 | 787, 93, 31, 31 |
787, 3, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 31 x 787 x 3 x 1 x 1 = 1463820
Therefore, the lowest common multiple of 787,186,620,620 is 1463820.
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.
787 x 186 x 620 x 620 = 56269240800
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.
787 : 1, 787
186 : 1, 2, 3, 6, 31, 62, 93, 186
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,186,620,620, is 1.
Now, the common factors can be found like this.
787:787
186:2x 3x 31
620:2x 2x 5x 31
620:2x 2x 5x 31
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 5x 31x 31 = 38440
Therefore, the value for common factors is 38440.
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 = 56269240800/(1x38440)
LCM = 56269240800/38440
LCM = 1463820
Thus, we can understand that the LCM of 787,186,620,620 is 1463820.
