HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 731, 222, 571 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 731, 222, 571 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 731, 222, 571 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 731, 222, 571 is 1.

HCF(731, 222, 571) = 1

Highest common factor (HCF) of 731, 222, 571 is 1.

Highest Common Factor of 731,222,571 using Euclid's algorithm

Highest Common Factor of 731,222,571 is 1

Step 1: Since 731 > 222, we apply the division lemma to 731 and 222, to get

731 = 222 x 3 + 65

Step 2: Since the reminder 222 ≠ 0, we apply division lemma to 65 and 222, to get

222 = 65 x 3 + 27

Step 3: We consider the new divisor 65 and the new remainder 27, and apply the division lemma to get

65 = 27 x 2 + 11

We consider the new divisor 27 and the new remainder 11,and apply the division lemma to get

27 = 11 x 2 + 5

We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get

11 = 5 x 2 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 731 and 222 is 1

Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(27,11) = HCF(65,27) = HCF(222,65) = HCF(731,222) .

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

Step 1: Since 571 > 1, we apply the division lemma to 571 and 1, to get

571 = 1 x 571 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 571 is 1

Notice that 1 = HCF(571,1) .
