HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 159, 831, 668, 683 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 159, 831, 668, 683 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 159, 831, 668, 683 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 159, 831, 668, 683 is 1.

HCF(159, 831, 668, 683) = 1

Highest common factor (HCF) of 159, 831, 668, 683 is 1.

Highest Common Factor of 159,831,668,683 using Euclid's algorithm

Highest Common Factor of 159,831,668,683 is 1

Step 1: Since 831 > 159, we apply the division lemma to 831 and 159, to get

831 = 159 x 5 + 36

Step 2: Since the reminder 159 ≠ 0, we apply division lemma to 36 and 159, to get

159 = 36 x 4 + 15

Step 3: We consider the new divisor 36 and the new remainder 15, and apply the division lemma to get

36 = 15 x 2 + 6

We consider the new divisor 15 and the new remainder 6,and apply the division lemma to get

15 = 6 x 2 + 3

We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get

6 = 3 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 159 and 831 is 3

Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(36,15) = HCF(159,36) = HCF(831,159) .

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

Step 1: Since 668 > 3, we apply the division lemma to 668 and 3, to get

668 = 3 x 222 + 2

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get

3 = 2 x 1 + 1

Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 668 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(668,3) .

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

Step 1: Since 683 > 1, we apply the division lemma to 683 and 1, to get

683 = 1 x 683 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 683 is 1

Notice that 1 = HCF(683,1) .
