HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 902, 487, 469 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 902, 487, 469 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 902, 487, 469 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 902, 487, 469 is 1.

HCF(902, 487, 469) = 1

Highest common factor (HCF) of 902, 487, 469 is 1.

Highest Common Factor of 902,487,469 using Euclid's algorithm

Highest Common Factor of 902,487,469 is 1

Step 1: Since 902 > 487, we apply the division lemma to 902 and 487, to get

902 = 487 x 1 + 415

Step 2: Since the reminder 487 ≠ 0, we apply division lemma to 415 and 487, to get

487 = 415 x 1 + 72

Step 3: We consider the new divisor 415 and the new remainder 72, and apply the division lemma to get

415 = 72 x 5 + 55

We consider the new divisor 72 and the new remainder 55,and apply the division lemma to get

72 = 55 x 1 + 17

We consider the new divisor 55 and the new remainder 17,and apply the division lemma to get

55 = 17 x 3 + 4

We consider the new divisor 17 and the new remainder 4,and apply the division lemma to get

17 = 4 x 4 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma 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 902 and 487 is 1

Notice that 1 = HCF(4,1) = HCF(17,4) = HCF(55,17) = HCF(72,55) = HCF(415,72) = HCF(487,415) = HCF(902,487) .

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

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

469 = 1 x 469 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 469 is 1

Notice that 1 = HCF(469,1) .
