HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 442, 256, 853 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 442, 256, 853 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 442, 256, 853 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 442, 256, 853 is 1.

HCF(442, 256, 853) = 1

Highest common factor (HCF) of 442, 256, 853 is 1.

Highest Common Factor of 442,256,853 using Euclid's algorithm

Highest Common Factor of 442,256,853 is 1

Step 1: Since 442 > 256, we apply the division lemma to 442 and 256, to get

442 = 256 x 1 + 186

Step 2: Since the reminder 256 ≠ 0, we apply division lemma to 186 and 256, to get

256 = 186 x 1 + 70

Step 3: We consider the new divisor 186 and the new remainder 70, and apply the division lemma to get

186 = 70 x 2 + 46

We consider the new divisor 70 and the new remainder 46,and apply the division lemma to get

70 = 46 x 1 + 24

We consider the new divisor 46 and the new remainder 24,and apply the division lemma to get

46 = 24 x 1 + 22

We consider the new divisor 24 and the new remainder 22,and apply the division lemma to get

24 = 22 x 1 + 2

We consider the new divisor 22 and the new remainder 2,and apply the division lemma to get

22 = 2 x 11 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 442 and 256 is 2

Notice that 2 = HCF(22,2) = HCF(24,22) = HCF(46,24) = HCF(70,46) = HCF(186,70) = HCF(256,186) = HCF(442,256) .

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

Step 1: Since 853 > 2, we apply the division lemma to 853 and 2, to get

853 = 2 x 426 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 853 is 1

Notice that 1 = HCF(2,1) = HCF(853,2) .
