Given numbers are 620,803,420,236,556
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 620,803,420,236,556 is 85741947060.
Find LCM of 620,803,420,236,556 with Prime Factorization
| 2 | 620, 803, 420, 236, 556 |
| 2 | 310, 803, 210, 118, 278 |
| 5 | 155, 803, 105, 59, 139 |
| 31, 803, 21, 59, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 31 x 803 x 21 x 59 x 139 = 85741947060
Therefore, the lowest common multiple of 620,803,420,236,556 is 85741947060.
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.
620 x 803 x 420 x 236 x 556 = 27437423059200
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.
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
803 : 1, 11, 73, 803
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
236 : 1, 2, 4, 59, 118, 236
556 : 1, 2, 4, 139, 278, 556
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,803,420,236,556, is 1.
Now, the common factors can be found like this.
620:2x 2x 5x 31
803:11x 73
420:2x 2x 3x 5x 7
236:2x 2x 59
556:2x 2x 139
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 5 = 320
Therefore, the value for common factors is 320.
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 = 27437423059200/(1x320)
LCM = 27437423059200/320
LCM = 85741947060
Thus, we can understand that the LCM of 620,803,420,236,556 is 85741947060.
