Given numbers are 974,812,861,618
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 974,812,861,618 is 5009880036.
Find LCM of 974,812,861,618 with Prime Factorization
| 2 | 974, 812, 861, 618 |
| 3 | 487, 406, 861, 309 |
| 7 | 487, 406, 287, 103 |
| 487, 58, 41, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 487 x 58 x 41 x 103 = 5009880036
Therefore, the lowest common multiple of 974,812,861,618 is 5009880036.
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 812 x 861 x 618 = 420829923024
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
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
861 : 1, 3, 7, 21, 41, 123, 287, 861
618 : 1, 2, 3, 6, 103, 206, 309, 618
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 974,812,861,618, is 1.
Now, the common factors can be found like this.
974:2x 487
812:2x 2x 7x 29
861:3x 7x 41
618:2x 3x 103
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 3x 7 = 84
Therefore, the value for common factors is 84.
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 = 420829923024/(1x84)
LCM = 420829923024/84
LCM = 5009880036
Thus, we can understand that the LCM of 974,812,861,618 is 5009880036.
