HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 469, 717, 124 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 469, 717, 124 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 469, 717, 124 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 469, 717, 124 is 1.

HCF(469, 717, 124) = 1

Highest common factor (HCF) of 469, 717, 124 is 1.

Highest Common Factor of 469,717,124 using Euclid's algorithm

Highest Common Factor of 469,717,124 is 1

Step 1: Since 717 > 469, we apply the division lemma to 717 and 469, to get

717 = 469 x 1 + 248

Step 2: Since the reminder 469 ≠ 0, we apply division lemma to 248 and 469, to get

469 = 248 x 1 + 221

Step 3: We consider the new divisor 248 and the new remainder 221, and apply the division lemma to get

248 = 221 x 1 + 27

We consider the new divisor 221 and the new remainder 27,and apply the division lemma to get

221 = 27 x 8 + 5

We consider the new divisor 27 and the new remainder 5,and apply the division lemma to get

27 = 5 x 5 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 469 and 717 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(27,5) = HCF(221,27) = HCF(248,221) = HCF(469,248) = HCF(717,469) .

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

Step 1: Since 124 > 1, we apply the division lemma to 124 and 1, to get

124 = 1 x 124 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 124 is 1

Notice that 1 = HCF(124,1) .
