HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 246, 415, 622 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 246, 415, 622 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 246, 415, 622 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 246, 415, 622 is 1.

HCF(246, 415, 622) = 1

HCF of 246, 415, 622 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 246, 415, 622 is 1.

Highest Common Factor of 246,415,622 using Euclid's algorithm

Highest Common Factor of 246,415,622 is 1

Step 1: Since 415 > 246, we apply the division lemma to 415 and 246, to get

415 = 246 x 1 + 169

Step 2: Since the reminder 246 ≠ 0, we apply division lemma to 169 and 246, to get

246 = 169 x 1 + 77

Step 3: We consider the new divisor 169 and the new remainder 77, and apply the division lemma to get

169 = 77 x 2 + 15

We consider the new divisor 77 and the new remainder 15,and apply the division lemma to get

77 = 15 x 5 + 2

We consider the new divisor 15 and the new remainder 2,and apply the division lemma to get

15 = 2 x 7 + 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 246 and 415 is 1

Notice that 1 = HCF(2,1) = HCF(15,2) = HCF(77,15) = HCF(169,77) = HCF(246,169) = HCF(415,246) .

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

Step 1: Since 622 > 1, we apply the division lemma to 622 and 1, to get

622 = 1 x 622 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 622 is 1

Notice that 1 = HCF(622,1) .
