HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 604, 156, 245 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 604, 156, 245 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 604, 156, 245 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 604, 156, 245 is 1.

HCF(604, 156, 245) = 1

HCF of 604, 156, 245 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 604, 156, 245 is 1.

Highest Common Factor of 604,156,245 using Euclid's algorithm

Highest Common Factor of 604,156,245 is 1

Step 1: Since 604 > 156, we apply the division lemma to 604 and 156, to get

604 = 156 x 3 + 136

Step 2: Since the reminder 156 ≠ 0, we apply division lemma to 136 and 156, to get

156 = 136 x 1 + 20

Step 3: We consider the new divisor 136 and the new remainder 20, and apply the division lemma to get

136 = 20 x 6 + 16

We consider the new divisor 20 and the new remainder 16,and apply the division lemma to get

20 = 16 x 1 + 4

We consider the new divisor 16 and the new remainder 4,and apply the division lemma to get

16 = 4 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 604 and 156 is 4

Notice that 4 = HCF(16,4) = HCF(20,16) = HCF(136,20) = HCF(156,136) = HCF(604,156) .

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

Step 1: Since 245 > 4, we apply the division lemma to 245 and 4, to get

245 = 4 x 61 + 1

Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 245 is 1

Notice that 1 = HCF(4,1) = HCF(245,4) .
