HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 379, 959, 780 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 379, 959, 780 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 379, 959, 780 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 379, 959, 780 is 1.

HCF(379, 959, 780) = 1

HCF of 379, 959, 780 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 379, 959, 780 is 1.

Highest Common Factor of 379,959,780 using Euclid's algorithm

Highest Common Factor of 379,959,780 is 1

Step 1: Since 959 > 379, we apply the division lemma to 959 and 379, to get

959 = 379 x 2 + 201

Step 2: Since the reminder 379 ≠ 0, we apply division lemma to 201 and 379, to get

379 = 201 x 1 + 178

Step 3: We consider the new divisor 201 and the new remainder 178, and apply the division lemma to get

201 = 178 x 1 + 23

We consider the new divisor 178 and the new remainder 23,and apply the division lemma to get

178 = 23 x 7 + 17

We consider the new divisor 23 and the new remainder 17,and apply the division lemma to get

23 = 17 x 1 + 6

We consider the new divisor 17 and the new remainder 6,and apply the division lemma to get

17 = 6 x 2 + 5

We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get

6 = 5 x 1 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 379 and 959 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(17,6) = HCF(23,17) = HCF(178,23) = HCF(201,178) = HCF(379,201) = HCF(959,379) .

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

Step 1: Since 780 > 1, we apply the division lemma to 780 and 1, to get

780 = 1 x 780 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 780 is 1

Notice that 1 = HCF(780,1) .
