HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 479, 858 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 479, 858 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 479, 858 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 479, 858 is 1.

HCF(479, 858) = 1

Highest common factor (HCF) of 479, 858 is 1.

Highest Common Factor of 479,858 using Euclid's algorithm

Highest Common Factor of 479,858 is 1

Step 1: Since 858 > 479, we apply the division lemma to 858 and 479, to get

858 = 479 x 1 + 379

Step 2: Since the reminder 479 ≠ 0, we apply division lemma to 379 and 479, to get

479 = 379 x 1 + 100

Step 3: We consider the new divisor 379 and the new remainder 100, and apply the division lemma to get

379 = 100 x 3 + 79

We consider the new divisor 100 and the new remainder 79,and apply the division lemma to get

100 = 79 x 1 + 21

We consider the new divisor 79 and the new remainder 21,and apply the division lemma to get

79 = 21 x 3 + 16

We consider the new divisor 21 and the new remainder 16,and apply the division lemma to get

21 = 16 x 1 + 5

We consider the new divisor 16 and the new remainder 5,and apply the division lemma to get

16 = 5 x 3 + 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 479 and 858 is 1

Notice that 1 = HCF(5,1) = HCF(16,5) = HCF(21,16) = HCF(79,21) = HCF(100,79) = HCF(379,100) = HCF(479,379) = HCF(858,479) .
