HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 428, 4425, 3079 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 428, 4425, 3079 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 428, 4425, 3079 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 428, 4425, 3079 is 1.

HCF(428, 4425, 3079) = 1

Highest Common Factor of 428,4425,3079 using Euclid's algorithm

Highest Common Factor of 428,4425,3079 is 1

Step 1: Since 4425 > 428, we apply the division lemma to 4425 and 428, to get

4425 = 428 x 10 + 145

Step 2: Since the reminder 428 ≠ 0, we apply division lemma to 145 and 428, to get

428 = 145 x 2 + 138

Step 3: We consider the new divisor 145 and the new remainder 138, and apply the division lemma to get

145 = 138 x 1 + 7

We consider the new divisor 138 and the new remainder 7,and apply the division lemma to get

138 = 7 x 19 + 5

We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get

7 = 5 x 1 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 428 and 4425 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(138,7) = HCF(145,138) = HCF(428,145) = HCF(4425,428) .

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

Step 1: Since 3079 > 1, we apply the division lemma to 3079 and 1, to get

3079 = 1 x 3079 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 3079 is 1

Notice that 1 = HCF(3079,1) .
