HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 221, 430, 887 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 221, 430, 887 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, 430, 887 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, 430, 887 is 1.

HCF(221, 430, 887) = 1

Highest common factor (HCF) of 221, 430, 887 is 1.

Highest Common Factor of 221,430,887 using Euclid's algorithm

Highest Common Factor of 221,430,887 is 1

Step 1: Since 430 > 221, we apply the division lemma to 430 and 221, to get

430 = 221 x 1 + 209

Step 2: Since the reminder 221 ≠ 0, we apply division lemma to 209 and 221, to get

221 = 209 x 1 + 12

Step 3: We consider the new divisor 209 and the new remainder 12, and apply the division lemma to get

209 = 12 x 17 + 5

We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get

12 = 5 x 2 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 221 and 430 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(209,12) = HCF(221,209) = HCF(430,221) .

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

Step 1: Since 887 > 1, we apply the division lemma to 887 and 1, to get

887 = 1 x 887 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 887 is 1

Notice that 1 = HCF(887,1) .
