HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 578, 775, 769 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 578, 775, 769 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 578, 775, 769 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 578, 775, 769 is 1.

HCF(578, 775, 769) = 1

HCF of 578, 775, 769 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 578, 775, 769 is 1.

Highest Common Factor of 578,775,769 using Euclid's algorithm

Highest Common Factor of 578,775,769 is 1

Step 1: Since 775 > 578, we apply the division lemma to 775 and 578, to get

775 = 578 x 1 + 197

Step 2: Since the reminder 578 ≠ 0, we apply division lemma to 197 and 578, to get

578 = 197 x 2 + 184

Step 3: We consider the new divisor 197 and the new remainder 184, and apply the division lemma to get

197 = 184 x 1 + 13

We consider the new divisor 184 and the new remainder 13,and apply the division lemma to get

184 = 13 x 14 + 2

We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get

13 = 2 x 6 + 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 578 and 775 is 1

Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(184,13) = HCF(197,184) = HCF(578,197) = HCF(775,578) .

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

Step 1: Since 769 > 1, we apply the division lemma to 769 and 1, to get

769 = 1 x 769 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 769 is 1

Notice that 1 = HCF(769,1) .
