HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 779, 221, 406, 14 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 779, 221, 406, 14 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 779, 221, 406, 14 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 779, 221, 406, 14 is 1.

HCF(779, 221, 406, 14) = 1

Highest Common Factor of 779,221,406,14 using Euclid's algorithm

Highest Common Factor of 779,221,406,14 is 1

Step 1: Since 779 > 221, we apply the division lemma to 779 and 221, to get

779 = 221 x 3 + 116

Step 2: Since the reminder 221 ≠ 0, we apply division lemma to 116 and 221, to get

221 = 116 x 1 + 105

Step 3: We consider the new divisor 116 and the new remainder 105, and apply the division lemma to get

116 = 105 x 1 + 11

We consider the new divisor 105 and the new remainder 11,and apply the division lemma to get

105 = 11 x 9 + 6

We consider the new divisor 11 and the new remainder 6,and apply the division lemma to get

11 = 6 x 1 + 5

We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get

6 = 5 x 1 + 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 779 and 221 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(105,11) = HCF(116,105) = HCF(221,116) = HCF(779,221) .


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

Step 1: Since 406 > 1, we apply the division lemma to 406 and 1, to get

406 = 1 x 406 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 406 is 1

Notice that 1 = HCF(406,1) .


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

Step 1: Since 14 > 1, we apply the division lemma to 14 and 1, to get

14 = 1 x 14 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 14 is 1

Notice that 1 = HCF(14,1) .
