HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 778, 955, 610 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 778, 955, 610 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 778, 955, 610 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 778, 955, 610 is 1.

HCF(778, 955, 610) = 1

HCF of 778, 955, 610 using Euclid's algorithm

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

Highest common factor (HCF) of 778, 955, 610 is 1.

Highest Common Factor of 778,955,610 using Euclid's algorithm

Highest Common Factor of 778,955,610 is 1

Step 1: Since 955 > 778, we apply the division lemma to 955 and 778, to get

955 = 778 x 1 + 177

Step 2: Since the reminder 778 ≠ 0, we apply division lemma to 177 and 778, to get

778 = 177 x 4 + 70

Step 3: We consider the new divisor 177 and the new remainder 70, and apply the division lemma to get

177 = 70 x 2 + 37

We consider the new divisor 70 and the new remainder 37,and apply the division lemma to get

70 = 37 x 1 + 33

We consider the new divisor 37 and the new remainder 33,and apply the division lemma to get

37 = 33 x 1 + 4

We consider the new divisor 33 and the new remainder 4,and apply the division lemma to get

33 = 4 x 8 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 778 and 955 is 1

Notice that 1 = HCF(4,1) = HCF(33,4) = HCF(37,33) = HCF(70,37) = HCF(177,70) = HCF(778,177) = HCF(955,778) .

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

Step 1: Since 610 > 1, we apply the division lemma to 610 and 1, to get

610 = 1 x 610 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 610 is 1

Notice that 1 = HCF(610,1) .
