HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 870, 545, 471 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 870, 545, 471 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 870, 545, 471 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 870, 545, 471 is 1.

HCF(870, 545, 471) = 1

Highest common factor (HCF) of 870, 545, 471 is 1.

Highest Common Factor of 870,545,471 using Euclid's algorithm

Highest Common Factor of 870,545,471 is 1

Step 1: Since 870 > 545, we apply the division lemma to 870 and 545, to get

870 = 545 x 1 + 325

Step 2: Since the reminder 545 ≠ 0, we apply division lemma to 325 and 545, to get

545 = 325 x 1 + 220

Step 3: We consider the new divisor 325 and the new remainder 220, and apply the division lemma to get

325 = 220 x 1 + 105

We consider the new divisor 220 and the new remainder 105,and apply the division lemma to get

220 = 105 x 2 + 10

We consider the new divisor 105 and the new remainder 10,and apply the division lemma to get

105 = 10 x 10 + 5

We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get

10 = 5 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 870 and 545 is 5

Notice that 5 = HCF(10,5) = HCF(105,10) = HCF(220,105) = HCF(325,220) = HCF(545,325) = HCF(870,545) .

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

Step 1: Since 471 > 5, we apply the division lemma to 471 and 5, to get

471 = 5 x 94 + 1

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 1 and 5, 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 5 and 471 is 1

Notice that 1 = HCF(5,1) = HCF(471,5) .
