HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 393, 604 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 393, 604 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 393, 604 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 393, 604 is 1.

HCF(393, 604) = 1

Highest common factor (HCF) of 393, 604 is 1.

Highest Common Factor of 393,604 using Euclid's algorithm

Highest Common Factor of 393,604 is 1

Step 1: Since 604 > 393, we apply the division lemma to 604 and 393, to get

604 = 393 x 1 + 211

Step 2: Since the reminder 393 ≠ 0, we apply division lemma to 211 and 393, to get

393 = 211 x 1 + 182

Step 3: We consider the new divisor 211 and the new remainder 182, and apply the division lemma to get

211 = 182 x 1 + 29

We consider the new divisor 182 and the new remainder 29,and apply the division lemma to get

182 = 29 x 6 + 8

We consider the new divisor 29 and the new remainder 8,and apply the division lemma to get

29 = 8 x 3 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 393 and 604 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(29,8) = HCF(182,29) = HCF(211,182) = HCF(393,211) = HCF(604,393) .
