HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 667, 861, 980, 629 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 667, 861, 980, 629 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 667, 861, 980, 629 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 667, 861, 980, 629 is 1.

HCF(667, 861, 980, 629) = 1

Highest common factor (HCF) of 667, 861, 980, 629 is 1.

Highest Common Factor of 667,861,980,629 using Euclid's algorithm

Highest Common Factor of 667,861,980,629 is 1

Step 1: Since 861 > 667, we apply the division lemma to 861 and 667, to get

861 = 667 x 1 + 194

Step 2: Since the reminder 667 ≠ 0, we apply division lemma to 194 and 667, to get

667 = 194 x 3 + 85

Step 3: We consider the new divisor 194 and the new remainder 85, and apply the division lemma to get

194 = 85 x 2 + 24

We consider the new divisor 85 and the new remainder 24,and apply the division lemma to get

85 = 24 x 3 + 13

We consider the new divisor 24 and the new remainder 13,and apply the division lemma to get

24 = 13 x 1 + 11

We consider the new divisor 13 and the new remainder 11,and apply the division lemma to get

13 = 11 x 1 + 2

We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get

11 = 2 x 5 + 1

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 667 and 861 is 1

Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(13,11) = HCF(24,13) = HCF(85,24) = HCF(194,85) = HCF(667,194) = HCF(861,667) .

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

Step 1: Since 980 > 1, we apply the division lemma to 980 and 1, to get

980 = 1 x 980 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 980 is 1

Notice that 1 = HCF(980,1) .

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

Step 1: Since 629 > 1, we apply the division lemma to 629 and 1, to get

629 = 1 x 629 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 629 is 1

Notice that 1 = HCF(629,1) .
