HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 771, 970, 435 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 771, 970, 435 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 771, 970, 435 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 771, 970, 435 is 1.

HCF(771, 970, 435) = 1

HCF of 771, 970, 435 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 771, 970, 435 is 1.

Highest Common Factor of 771,970,435 using Euclid's algorithm

Highest Common Factor of 771,970,435 is 1

Step 1: Since 970 > 771, we apply the division lemma to 970 and 771, to get

970 = 771 x 1 + 199

Step 2: Since the reminder 771 ≠ 0, we apply division lemma to 199 and 771, to get

771 = 199 x 3 + 174

Step 3: We consider the new divisor 199 and the new remainder 174, and apply the division lemma to get

199 = 174 x 1 + 25

We consider the new divisor 174 and the new remainder 25,and apply the division lemma to get

174 = 25 x 6 + 24

We consider the new divisor 25 and the new remainder 24,and apply the division lemma to get

25 = 24 x 1 + 1

We consider the new divisor 24 and the new remainder 1,and apply the division lemma to get

24 = 1 x 24 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 771 and 970 is 1

Notice that 1 = HCF(24,1) = HCF(25,24) = HCF(174,25) = HCF(199,174) = HCF(771,199) = HCF(970,771) .

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

Step 1: Since 435 > 1, we apply the division lemma to 435 and 1, to get

435 = 1 x 435 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 435 is 1

Notice that 1 = HCF(435,1) .
