HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 861, 953, 788 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 861, 953, 788 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 861, 953, 788 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 861, 953, 788 is 1.

HCF(861, 953, 788) = 1

Highest common factor (HCF) of 861, 953, 788 is 1.

Highest Common Factor of 861,953,788 using Euclid's algorithm

Highest Common Factor of 861,953,788 is 1

Step 1: Since 953 > 861, we apply the division lemma to 953 and 861, to get

953 = 861 x 1 + 92

Step 2: Since the reminder 861 ≠ 0, we apply division lemma to 92 and 861, to get

861 = 92 x 9 + 33

Step 3: We consider the new divisor 92 and the new remainder 33, and apply the division lemma to get

92 = 33 x 2 + 26

We consider the new divisor 33 and the new remainder 26,and apply the division lemma to get

33 = 26 x 1 + 7

We consider the new divisor 26 and the new remainder 7,and apply the division lemma to get

26 = 7 x 3 + 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 861 and 953 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(26,7) = HCF(33,26) = HCF(92,33) = HCF(861,92) = HCF(953,861) .

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

Step 1: Since 788 > 1, we apply the division lemma to 788 and 1, to get

788 = 1 x 788 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 788 is 1

Notice that 1 = HCF(788,1) .
