Calculate the LCM of 905,942,847,415,938

Given numbers are 905,942,847,415,938

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 905,942,847,415,938 is 4015464469170.

Find LCM of 905,942,847,415,938 with Prime Factorization


2 905, 942, 847, 415, 938
5 905, 471, 847, 415, 469
7 181, 471, 847, 83, 469
181, 471, 121, 83, 67

Multiply the prime numbers at the bottom and the left side.

2 x 5 x 7 x 181 x 471 x 121 x 83 x 67 = 4015464469170

Therefore, the lowest common multiple of 905,942,847,415,938 is 4015464469170.

LCM Formula to Find Lowest Common Multiple of 905,942,847,415,938

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.

905 x 942 x 847 x 415 x 938 = 281082512841900

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.

905 : 1, 5, 181, 905

942 : 1, 2, 3, 6, 157, 314, 471, 942

847 : 1, 7, 11, 77, 121, 847

415 : 1, 5, 83, 415

938 : 1, 2, 7, 14, 67, 134, 469, 938

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,942,847,415,938, is 1.

Now, the common factors can be found like this.

905:5x 181

942:2x 3x 157

847:7x 11x 11

415:5x 83

938:2x 7x 67

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 5x 7 = 70

Therefore, the value for common factors is 70.

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 = 281082512841900/(1x70)

LCM = 281082512841900/70

LCM = 4015464469170

Thus, we can understand that the LCM of 905,942,847,415,938 is 4015464469170.
