HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 471, 290 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 471, 290 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 471, 290 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 471, 290 is 1.

HCF(471, 290) = 1

Highest common factor (HCF) of 471, 290 is 1.

Highest Common Factor of 471,290 using Euclid's algorithm

Highest Common Factor of 471,290 is 1

Step 1: Since 471 > 290, we apply the division lemma to 471 and 290, to get

471 = 290 x 1 + 181

Step 2: Since the reminder 290 ≠ 0, we apply division lemma to 181 and 290, to get

290 = 181 x 1 + 109

Step 3: We consider the new divisor 181 and the new remainder 109, and apply the division lemma to get

181 = 109 x 1 + 72

We consider the new divisor 109 and the new remainder 72,and apply the division lemma to get

109 = 72 x 1 + 37

We consider the new divisor 72 and the new remainder 37,and apply the division lemma to get

72 = 37 x 1 + 35

We consider the new divisor 37 and the new remainder 35,and apply the division lemma to get

37 = 35 x 1 + 2

We consider the new divisor 35 and the new remainder 2,and apply the division lemma to get

35 = 2 x 17 + 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 471 and 290 is 1

Notice that 1 = HCF(2,1) = HCF(35,2) = HCF(37,35) = HCF(72,37) = HCF(109,72) = HCF(181,109) = HCF(290,181) = HCF(471,290) .
