Given numbers are 651,911,620,761,854
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 651,911,620,761,854 is 550609693620.
Find LCM of 651,911,620,761,854 with Prime Factorization
| 2 | 651, 911, 620, 761, 854 |
| 7 | 651, 911, 310, 761, 427 |
| 31 | 93, 911, 310, 761, 61 |
| 3, 911, 10, 761, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 31 x 3 x 911 x 10 x 761 x 61 = 550609693620
Therefore, the lowest common multiple of 651,911,620,761,854 is 550609693620.
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.
651 x 911 x 620 x 761 x 854 = 238964607031080
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.
651 : 1, 3, 7, 21, 31, 93, 217, 651
911 : 1, 911
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
761 : 1, 761
854 : 1, 2, 7, 14, 61, 122, 427, 854
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 651,911,620,761,854, is 1.
Now, the common factors can be found like this.
651:3x 7x 31
911:911
620:2x 2x 5x 31
761:761
854:2x 7x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 31 = 434
Therefore, the value for common factors is 434.
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 = 238964607031080/(1x434)
LCM = 238964607031080/434
LCM = 550609693620
Thus, we can understand that the LCM of 651,911,620,761,854 is 550609693620.
