HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 722, 557, 343 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 722, 557, 343 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, 557, 343 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, 557, 343 is 1.

HCF(722, 557, 343) = 1

Highest common factor (HCF) of 722, 557, 343 is 1.

Highest Common Factor of 722,557,343 using Euclid's algorithm

Highest Common Factor of 722,557,343 is 1

Step 1: Since 722 > 557, we apply the division lemma to 722 and 557, to get

722 = 557 x 1 + 165

Step 2: Since the reminder 557 ≠ 0, we apply division lemma to 165 and 557, to get

557 = 165 x 3 + 62

Step 3: We consider the new divisor 165 and the new remainder 62, and apply the division lemma to get

165 = 62 x 2 + 41

We consider the new divisor 62 and the new remainder 41,and apply the division lemma to get

62 = 41 x 1 + 21

We consider the new divisor 41 and the new remainder 21,and apply the division lemma to get

41 = 21 x 1 + 20

We consider the new divisor 21 and the new remainder 20,and apply the division lemma to get

21 = 20 x 1 + 1

We consider the new divisor 20 and the new remainder 1,and apply the division lemma to get

20 = 1 x 20 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 722 and 557 is 1

Notice that 1 = HCF(20,1) = HCF(21,20) = HCF(41,21) = HCF(62,41) = HCF(165,62) = HCF(557,165) = HCF(722,557) .

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

Step 1: Since 343 > 1, we apply the division lemma to 343 and 1, to get

343 = 1 x 343 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 343 is 1

Notice that 1 = HCF(343,1) .
