Calculate the LCM of 785,697,605,697

Given numbers are 785,697,605,697

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

The LCM of 785,697,605,697 is 66204545.

Find LCM of 785,697,605,697 with Prime Factorization


5 785, 697, 605, 697
17 157, 697, 121, 697
41 157, 41, 121, 41
157, 1, 121, 1

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

5 x 17 x 41 x 157 x 1 x 121 x 1 = 66204545

Therefore, the lowest common multiple of 785,697,605,697 is 66204545.

LCM Formula to Find Lowest Common Multiple of 785,697,605,697

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.

785 x 697 x 605 x 697 = 230722839325

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.

785 : 1, 5, 157, 785

697 : 1, 17, 41, 697

605 : 1, 5, 11, 55, 121, 605

697 : 1, 17, 41, 697

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,697,605,697, is 1.

Now, the common factors can be found like this.

785:5x 157

697:17x 41

605:5x 11x 11

697:17x 41

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

5x 17x 41 = 3485

Therefore, the value for common factors is 3485.

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 = 230722839325/(1x3485)

LCM = 230722839325/3485

LCM = 66204545

Thus, we can understand that the LCM of 785,697,605,697 is 66204545.
