Given numbers are 553,973,278,171,787
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 553,973,278,171,787 is 20689060518.
Find LCM of 553,973,278,171,787 with Prime Factorization
| 7 | 553, 973, 278, 171, 787 |
| 139 | 79, 139, 278, 171, 787 |
| 79, 1, 2, 171, 787 |
Multiply the prime numbers at the bottom and the left side.
7 x 139 x 79 x 1 x 2 x 171 x 787 = 20689060518
Therefore, the lowest common multiple of 553,973,278,171,787 is 20689060518.
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.
553 x 973 x 278 x 171 x 787 = 20130455884014
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.
553 : 1, 7, 79, 553
973 : 1, 7, 139, 973
278 : 1, 2, 139, 278
171 : 1, 3, 9, 19, 57, 171
787 : 1, 787
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 553,973,278,171,787, is 1.
Now, the common factors can be found like this.
553:7x 79
973:7x 139
278:2x 139
171:3x 3x 19
787:787
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 139 = 973
Therefore, the value for common factors is 973.
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 = 20130455884014/(1x973)
LCM = 20130455884014/973
LCM = 20689060518
Thus, we can understand that the LCM of 553,973,278,171,787 is 20689060518.
