HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 522, 379, 686 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 522, 379, 686 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 522, 379, 686 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 522, 379, 686 is 1.

HCF(522, 379, 686) = 1

Highest common factor (HCF) of 522, 379, 686 is 1.

Highest Common Factor of 522,379,686 using Euclid's algorithm

Highest Common Factor of 522,379,686 is 1

Step 1: Since 522 > 379, we apply the division lemma to 522 and 379, to get

522 = 379 x 1 + 143

Step 2: Since the reminder 379 ≠ 0, we apply division lemma to 143 and 379, to get

379 = 143 x 2 + 93

Step 3: We consider the new divisor 143 and the new remainder 93, and apply the division lemma to get

143 = 93 x 1 + 50

We consider the new divisor 93 and the new remainder 50,and apply the division lemma to get

93 = 50 x 1 + 43

We consider the new divisor 50 and the new remainder 43,and apply the division lemma to get

50 = 43 x 1 + 7

We consider the new divisor 43 and the new remainder 7,and apply the division lemma to get

43 = 7 x 6 + 1

We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get

7 = 1 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 522 and 379 is 1

Notice that 1 = HCF(7,1) = HCF(43,7) = HCF(50,43) = HCF(93,50) = HCF(143,93) = HCF(379,143) = HCF(522,379) .

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

Step 1: Since 686 > 1, we apply the division lemma to 686 and 1, to get

686 = 1 x 686 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 686 is 1

Notice that 1 = HCF(686,1) .
