HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 388, 685, 944 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 388, 685, 944 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.

Consider we have numbers 388, 685, 944 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b

Highest common factor (HCF) of 388, 685, 944 is 1.

HCF(388, 685, 944) = 1

Highest common factor (HCF) of 388, 685, 944 is 1.

Highest Common Factor of 388,685,944 using Euclid's algorithm

Highest Common Factor of 388,685,944 is 1

Step 1: Since 685 > 388, we apply the division lemma to 685 and 388, to get

685 = 388 x 1 + 297

Step 2: Since the reminder 388 ≠ 0, we apply division lemma to 297 and 388, to get

388 = 297 x 1 + 91

Step 3: We consider the new divisor 297 and the new remainder 91, and apply the division lemma to get

297 = 91 x 3 + 24

We consider the new divisor 91 and the new remainder 24,and apply the division lemma to get

91 = 24 x 3 + 19

We consider the new divisor 24 and the new remainder 19,and apply the division lemma to get

24 = 19 x 1 + 5

We consider the new divisor 19 and the new remainder 5,and apply the division lemma to get

19 = 5 x 3 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 388 and 685 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(19,5) = HCF(24,19) = HCF(91,24) = HCF(297,91) = HCF(388,297) = HCF(685,388) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 944 > 1, we apply the division lemma to 944 and 1, to get

944 = 1 x 944 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 944 is 1

Notice that 1 = HCF(944,1) .
