HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 863, 153, 608 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 863, 153, 608 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 863, 153, 608 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 863, 153, 608 is 1.

HCF(863, 153, 608) = 1

HCF of 863, 153, 608 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 863, 153, 608 is 1.

Highest Common Factor of 863,153,608 using Euclid's algorithm

Highest Common Factor of 863,153,608 is 1

Step 1: Since 863 > 153, we apply the division lemma to 863 and 153, to get

863 = 153 x 5 + 98

Step 2: Since the reminder 153 ≠ 0, we apply division lemma to 98 and 153, to get

153 = 98 x 1 + 55

Step 3: We consider the new divisor 98 and the new remainder 55, and apply the division lemma to get

98 = 55 x 1 + 43

We consider the new divisor 55 and the new remainder 43,and apply the division lemma to get

55 = 43 x 1 + 12

We consider the new divisor 43 and the new remainder 12,and apply the division lemma to get

43 = 12 x 3 + 7

We consider the new divisor 12 and the new remainder 7,and apply the division lemma to get

12 = 7 x 1 + 5

We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get

7 = 5 x 1 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 863 and 153 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(12,7) = HCF(43,12) = HCF(55,43) = HCF(98,55) = HCF(153,98) = HCF(863,153) .

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

Step 1: Since 608 > 1, we apply the division lemma to 608 and 1, to get

608 = 1 x 608 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 608 is 1

Notice that 1 = HCF(608,1) .
