Given numbers are 154,688,642,658,676
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 154,688,642,658,676 is 135073066128.
Find LCM of 154,688,642,658,676 with Prime Factorization
2 | 154, 688, 642, 658, 676 |
2 | 77, 344, 321, 329, 338 |
7 | 77, 172, 321, 329, 169 |
11, 172, 321, 47, 169 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 11 x 172 x 321 x 47 x 169 = 135073066128
Therefore, the lowest common multiple of 154,688,642,658,676 is 135073066128.
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.
154 x 688 x 642 x 658 x 676 = 30256366812672
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.
154 : 1, 2, 7, 11, 14, 22, 77, 154
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
642 : 1, 2, 3, 6, 107, 214, 321, 642
658 : 1, 2, 7, 14, 47, 94, 329, 658
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 154,688,642,658,676, is 2.
Now, the common factors can be found like this.
154:2x 7x 11
688:2x 2x 2x 2x 43
642:2x 3x 107
658:2x 7x 47
676:2x 2x 13x 13
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 7 = 112
Therefore, the value for common factors is 112.
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 = 30256366812672/(2x112)
LCM = 30256366812672/224
LCM = 135073066128
Thus, we can understand that the LCM of 154,688,642,658,676 is 135073066128.
