HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 547, 870 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 547, 870 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 547, 870 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 547, 870 is 1.

HCF(547, 870) = 1

Highest common factor (HCF) of 547, 870 is 1.

Highest Common Factor of 547,870 using Euclid's algorithm

Highest Common Factor of 547,870 is 1

Step 1: Since 870 > 547, we apply the division lemma to 870 and 547, to get

870 = 547 x 1 + 323

Step 2: Since the reminder 547 ≠ 0, we apply division lemma to 323 and 547, to get

547 = 323 x 1 + 224

Step 3: We consider the new divisor 323 and the new remainder 224, and apply the division lemma to get

323 = 224 x 1 + 99

We consider the new divisor 224 and the new remainder 99,and apply the division lemma to get

224 = 99 x 2 + 26

We consider the new divisor 99 and the new remainder 26,and apply the division lemma to get

99 = 26 x 3 + 21

We consider the new divisor 26 and the new remainder 21,and apply the division lemma to get

26 = 21 x 1 + 5

We consider the new divisor 21 and the new remainder 5,and apply the division lemma to get

21 = 5 x 4 + 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 547 and 870 is 1

Notice that 1 = HCF(5,1) = HCF(21,5) = HCF(26,21) = HCF(99,26) = HCF(224,99) = HCF(323,224) = HCF(547,323) = HCF(870,547) .
