HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 431, 657, 668, 361 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 431, 657, 668, 361 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 431, 657, 668, 361 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 431, 657, 668, 361 is 1.

HCF(431, 657, 668, 361) = 1

Highest Common Factor of 431,657,668,361 using Euclid's algorithm

Highest Common Factor of 431,657,668,361 is 1

Step 1: Since 657 > 431, we apply the division lemma to 657 and 431, to get

657 = 431 x 1 + 226

Step 2: Since the reminder 431 ≠ 0, we apply division lemma to 226 and 431, to get

431 = 226 x 1 + 205

Step 3: We consider the new divisor 226 and the new remainder 205, and apply the division lemma to get

226 = 205 x 1 + 21

We consider the new divisor 205 and the new remainder 21,and apply the division lemma to get

205 = 21 x 9 + 16

We consider the new divisor 21 and the new remainder 16,and apply the division lemma to get

21 = 16 x 1 + 5

We consider the new divisor 16 and the new remainder 5,and apply the division lemma to get

16 = 5 x 3 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 431 and 657 is 1

Notice that 1 = HCF(5,1) = HCF(16,5) = HCF(21,16) = HCF(205,21) = HCF(226,205) = HCF(431,226) = HCF(657,431) .

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

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

668 = 1 x 668 + 0

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

Notice that 1 = HCF(668,1) .

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

Step 1: Since 361 > 1, we apply the division lemma to 361 and 1, to get

361 = 1 x 361 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 361 is 1

Notice that 1 = HCF(361,1) .
