HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 858, 479, 377 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 858, 479, 377 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 858, 479, 377 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 858, 479, 377 is 1.

HCF(858, 479, 377) = 1

HCF of 858, 479, 377 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 858, 479, 377 is 1.

Highest Common Factor of 858,479,377 using Euclid's algorithm

Highest Common Factor of 858,479,377 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 858 and 479 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) .

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

Step 1: Since 377 > 1, we apply the division lemma to 377 and 1, to get

377 = 1 x 377 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 377 is 1

Notice that 1 = HCF(377,1) .
