Calculate the LCM of 978,785,222,743

Given numbers are 978,785,222,743

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

The LCM of 978,785,222,743 is 21105665430.

Find LCM of 978,785,222,743 with Prime Factorization


2 978, 785, 222, 743
3 489, 785, 111, 743
163, 785, 37, 743

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

2 x 3 x 163 x 785 x 37 x 743 = 21105665430

Therefore, the lowest common multiple of 978,785,222,743 is 21105665430.

LCM Formula to Find Lowest Common Multiple of 978,785,222,743

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.

978 x 785 x 222 x 743 = 126633992580

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.

978 : 1, 2, 3, 6, 163, 326, 489, 978

785 : 1, 5, 157, 785

222 : 1, 2, 3, 6, 37, 74, 111, 222

743 : 1, 743

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,785,222,743, is 1.

Now, the common factors can be found like this.

978:2x 3x 163

785:5x 157

222:2x 3x 37

743:743

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 126633992580/(1x6)

LCM = 126633992580/6

LCM = 21105665430

Thus, we can understand that the LCM of 978,785,222,743 is 21105665430.
