HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 497, 690, 154, 41 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 497, 690, 154, 41 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 497, 690, 154, 41 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 497, 690, 154, 41 is 1.

HCF(497, 690, 154, 41) = 1

Highest Common Factor of 497,690,154,41 using Euclid's algorithm

Highest Common Factor of 497,690,154,41 is 1

Step 1: Since 690 > 497, we apply the division lemma to 690 and 497, to get

690 = 497 x 1 + 193

Step 2: Since the reminder 497 ≠ 0, we apply division lemma to 193 and 497, to get

497 = 193 x 2 + 111

Step 3: We consider the new divisor 193 and the new remainder 111, and apply the division lemma to get

193 = 111 x 1 + 82

We consider the new divisor 111 and the new remainder 82,and apply the division lemma to get

111 = 82 x 1 + 29

We consider the new divisor 82 and the new remainder 29,and apply the division lemma to get

82 = 29 x 2 + 24

We consider the new divisor 29 and the new remainder 24,and apply the division lemma to get

29 = 24 x 1 + 5

We consider the new divisor 24 and the new remainder 5,and apply the division lemma to get

24 = 5 x 4 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 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 497 and 690 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(24,5) = HCF(29,24) = HCF(82,29) = HCF(111,82) = HCF(193,111) = HCF(497,193) = HCF(690,497) .

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

Step 1: Since 154 > 1, we apply the division lemma to 154 and 1, to get

154 = 1 x 154 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 154 is 1

Notice that 1 = HCF(154,1) .

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

Step 1: Since 41 > 1, we apply the division lemma to 41 and 1, to get

41 = 1 x 41 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 41 is 1

Notice that 1 = HCF(41,1) .
