HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 221, 579, 674, 207 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 221, 579, 674, 207 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 221, 579, 674, 207 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 221, 579, 674, 207 is 1.

HCF(221, 579, 674, 207) = 1

Highest Common Factor of 221,579,674,207 using Euclid's algorithm

Highest Common Factor of 221,579,674,207 is 1

Step 1: Since 579 > 221, we apply the division lemma to 579 and 221, to get

579 = 221 x 2 + 137

Step 2: Since the reminder 221 ≠ 0, we apply division lemma to 137 and 221, to get

221 = 137 x 1 + 84

Step 3: We consider the new divisor 137 and the new remainder 84, and apply the division lemma to get

137 = 84 x 1 + 53

We consider the new divisor 84 and the new remainder 53,and apply the division lemma to get

84 = 53 x 1 + 31

We consider the new divisor 53 and the new remainder 31,and apply the division lemma to get

53 = 31 x 1 + 22

We consider the new divisor 31 and the new remainder 22,and apply the division lemma to get

31 = 22 x 1 + 9

We consider the new divisor 22 and the new remainder 9,and apply the division lemma to get

22 = 9 x 2 + 4

We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get

9 = 4 x 2 + 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 221 and 579 is 1

Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(22,9) = HCF(31,22) = HCF(53,31) = HCF(84,53) = HCF(137,84) = HCF(221,137) = HCF(579,221) .

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

Step 1: Since 674 > 1, we apply the division lemma to 674 and 1, to get

674 = 1 x 674 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 674 is 1

Notice that 1 = HCF(674,1) .

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

Step 1: Since 207 > 1, we apply the division lemma to 207 and 1, to get

207 = 1 x 207 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 207 is 1

Notice that 1 = HCF(207,1) .
