Given numbers are 624,421,715,791,457
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 624,421,715,791,457 is 5223024446640.
Find LCM of 624,421,715,791,457 with Prime Factorization
13 | 624, 421, 715, 791, 457 |
48, 421, 55, 791, 457 |
Multiply the prime numbers at the bottom and the left side.
13 x 48 x 421 x 55 x 791 x 457 = 5223024446640
Therefore, the lowest common multiple of 624,421,715,791,457 is 5223024446640.
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.
624 x 421 x 715 x 791 x 457 = 67899317806320
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.
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
421 : 1, 421
715 : 1, 5, 11, 13, 55, 65, 143, 715
791 : 1, 7, 113, 791
457 : 1, 457
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 624,421,715,791,457, is 1.
Now, the common factors can be found like this.
624:2x 2x 2x 2x 3x 13
421:421
715:5x 11x 13
791:7x 113
457:457
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13 = 13
Therefore, the value for common factors is 13.
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 = 67899317806320/(1x13)
LCM = 67899317806320/13
LCM = 5223024446640
Thus, we can understand that the LCM of 624,421,715,791,457 is 5223024446640.
