HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 149, 557, 394 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 149, 557, 394 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 149, 557, 394 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 149, 557, 394 is 1.

HCF(149, 557, 394) = 1

Highest common factor (HCF) of 149, 557, 394 is 1.

Highest Common Factor of 149,557,394 using Euclid's algorithm

Highest Common Factor of 149,557,394 is 1

Step 1: Since 557 > 149, we apply the division lemma to 557 and 149, to get

557 = 149 x 3 + 110

Step 2: Since the reminder 149 ≠ 0, we apply division lemma to 110 and 149, to get

149 = 110 x 1 + 39

Step 3: We consider the new divisor 110 and the new remainder 39, and apply the division lemma to get

110 = 39 x 2 + 32

We consider the new divisor 39 and the new remainder 32,and apply the division lemma to get

39 = 32 x 1 + 7

We consider the new divisor 32 and the new remainder 7,and apply the division lemma to get

32 = 7 x 4 + 4

We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get

7 = 4 x 1 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 149 and 557 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(32,7) = HCF(39,32) = HCF(110,39) = HCF(149,110) = HCF(557,149) .

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

Step 1: Since 394 > 1, we apply the division lemma to 394 and 1, to get

394 = 1 x 394 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 394 is 1

Notice that 1 = HCF(394,1) .
