HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 690, 469, 577 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 690, 469, 577 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 690, 469, 577 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 690, 469, 577 is 1.

HCF(690, 469, 577) = 1

HCF of 690, 469, 577 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

Highest common factor (HCF) of 690, 469, 577 is 1.

Highest Common Factor of 690,469,577 using Euclid's algorithm

Highest Common Factor of 690,469,577 is 1

Step 1: Since 690 > 469, we apply the division lemma to 690 and 469, to get

690 = 469 x 1 + 221

Step 2: Since the reminder 469 ≠ 0, we apply division lemma to 221 and 469, to get

469 = 221 x 2 + 27

Step 3: 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 690 and 469 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(27,5) = HCF(221,27) = HCF(469,221) = HCF(690,469) .

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

Step 1: Since 577 > 1, we apply the division lemma to 577 and 1, to get

577 = 1 x 577 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 577 is 1

Notice that 1 = HCF(577,1) .
