HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 855, 362, 278 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 855, 362, 278 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 855, 362, 278 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 855, 362, 278 is 1.

HCF(855, 362, 278) = 1

Highest common factor (HCF) of 855, 362, 278 is 1.

Highest Common Factor of 855,362,278 using Euclid's algorithm

Highest Common Factor of 855,362,278 is 1

Step 1: Since 855 > 362, we apply the division lemma to 855 and 362, to get

855 = 362 x 2 + 131

Step 2: Since the reminder 362 ≠ 0, we apply division lemma to 131 and 362, to get

362 = 131 x 2 + 100

Step 3: We consider the new divisor 131 and the new remainder 100, and apply the division lemma to get

131 = 100 x 1 + 31

We consider the new divisor 100 and the new remainder 31,and apply the division lemma to get

100 = 31 x 3 + 7

We consider the new divisor 31 and the new remainder 7,and apply the division lemma to get

31 = 7 x 4 + 3

We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get

7 = 3 x 2 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 855 and 362 is 1

Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(31,7) = HCF(100,31) = HCF(131,100) = HCF(362,131) = HCF(855,362) .

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

Step 1: Since 278 > 1, we apply the division lemma to 278 and 1, to get

278 = 1 x 278 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 278 is 1

Notice that 1 = HCF(278,1) .
