HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 818, 343, 392 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 818, 343, 392 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 818, 343, 392 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 818, 343, 392 is 1.

HCF(818, 343, 392) = 1

Highest common factor (HCF) of 818, 343, 392 is 1.

Highest Common Factor of 818,343,392 using Euclid's algorithm

Highest Common Factor of 818,343,392 is 1

Step 1: Since 818 > 343, we apply the division lemma to 818 and 343, to get

818 = 343 x 2 + 132

Step 2: Since the reminder 343 ≠ 0, we apply division lemma to 132 and 343, to get

343 = 132 x 2 + 79

Step 3: We consider the new divisor 132 and the new remainder 79, and apply the division lemma to get

132 = 79 x 1 + 53

We consider the new divisor 79 and the new remainder 53,and apply the division lemma to get

79 = 53 x 1 + 26

We consider the new divisor 53 and the new remainder 26,and apply the division lemma to get

53 = 26 x 2 + 1

We consider the new divisor 26 and the new remainder 1,and apply the division lemma to get

26 = 1 x 26 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 818 and 343 is 1

Notice that 1 = HCF(26,1) = HCF(53,26) = HCF(79,53) = HCF(132,79) = HCF(343,132) = HCF(818,343) .

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

Step 1: Since 392 > 1, we apply the division lemma to 392 and 1, to get

392 = 1 x 392 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 392 is 1

Notice that 1 = HCF(392,1) .
