HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 722, 467, 647 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 722, 467, 647 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 722, 467, 647 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 722, 467, 647 is 1.

HCF(722, 467, 647) = 1

Highest common factor (HCF) of 722, 467, 647 is 1.

Highest Common Factor of 722,467,647 using Euclid's algorithm

Highest Common Factor of 722,467,647 is 1

Step 1: Since 722 > 467, we apply the division lemma to 722 and 467, to get

722 = 467 x 1 + 255

Step 2: Since the reminder 467 ≠ 0, we apply division lemma to 255 and 467, to get

467 = 255 x 1 + 212

Step 3: We consider the new divisor 255 and the new remainder 212, and apply the division lemma to get

255 = 212 x 1 + 43

We consider the new divisor 212 and the new remainder 43,and apply the division lemma to get

212 = 43 x 4 + 40

We consider the new divisor 43 and the new remainder 40,and apply the division lemma to get

43 = 40 x 1 + 3

We consider the new divisor 40 and the new remainder 3,and apply the division lemma to get

40 = 3 x 13 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 722 and 467 is 1

Notice that 1 = HCF(3,1) = HCF(40,3) = HCF(43,40) = HCF(212,43) = HCF(255,212) = HCF(467,255) = HCF(722,467) .

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

Step 1: Since 647 > 1, we apply the division lemma to 647 and 1, to get

647 = 1 x 647 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 647 is 1

Notice that 1 = HCF(647,1) .
