HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 454, 761, 620 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 454, 761, 620 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 454, 761, 620 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 454, 761, 620 is 1.

HCF(454, 761, 620) = 1

HCF of 454, 761, 620 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 454, 761, 620 is 1.

Highest Common Factor of 454,761,620 using Euclid's algorithm

Highest Common Factor of 454,761,620 is 1

Step 1: Since 761 > 454, we apply the division lemma to 761 and 454, to get

761 = 454 x 1 + 307

Step 2: Since the reminder 454 ≠ 0, we apply division lemma to 307 and 454, to get

454 = 307 x 1 + 147

Step 3: We consider the new divisor 307 and the new remainder 147, and apply the division lemma to get

307 = 147 x 2 + 13

We consider the new divisor 147 and the new remainder 13,and apply the division lemma to get

147 = 13 x 11 + 4

We consider the new divisor 13 and the new remainder 4,and apply the division lemma to get

13 = 4 x 3 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 454 and 761 is 1

Notice that 1 = HCF(4,1) = HCF(13,4) = HCF(147,13) = HCF(307,147) = HCF(454,307) = HCF(761,454) .

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

Step 1: Since 620 > 1, we apply the division lemma to 620 and 1, to get

620 = 1 x 620 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 620 is 1

Notice that 1 = HCF(620,1) .
