HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 425, 658, 385 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 425, 658, 385 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 425, 658, 385 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 425, 658, 385 is 1.

HCF(425, 658, 385) = 1

HCF of 425, 658, 385 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 425, 658, 385 is 1.

Highest Common Factor of 425,658,385 using Euclid's algorithm

Highest Common Factor of 425,658,385 is 1

Step 1: Since 658 > 425, we apply the division lemma to 658 and 425, to get

658 = 425 x 1 + 233

Step 2: Since the reminder 425 ≠ 0, we apply division lemma to 233 and 425, to get

425 = 233 x 1 + 192

Step 3: We consider the new divisor 233 and the new remainder 192, and apply the division lemma to get

233 = 192 x 1 + 41

We consider the new divisor 192 and the new remainder 41,and apply the division lemma to get

192 = 41 x 4 + 28

We consider the new divisor 41 and the new remainder 28,and apply the division lemma to get

41 = 28 x 1 + 13

We consider the new divisor 28 and the new remainder 13,and apply the division lemma to get

28 = 13 x 2 + 2

We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get

13 = 2 x 6 + 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 425 and 658 is 1

Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(28,13) = HCF(41,28) = HCF(192,41) = HCF(233,192) = HCF(425,233) = HCF(658,425) .

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

Step 1: Since 385 > 1, we apply the division lemma to 385 and 1, to get

385 = 1 x 385 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 385 is 1

Notice that 1 = HCF(385,1) .
