HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 149, 423, 387, 539 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 149, 423, 387, 539 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, 423, 387, 539 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, 423, 387, 539 is 1.

HCF(149, 423, 387, 539) = 1

Highest common factor (HCF) of 149, 423, 387, 539 is 1.

Highest Common Factor of 149,423,387,539 using Euclid's algorithm

Highest Common Factor of 149,423,387,539 is 1

Step 1: Since 423 > 149, we apply the division lemma to 423 and 149, to get

423 = 149 x 2 + 125

Step 2: Since the reminder 149 ≠ 0, we apply division lemma to 125 and 149, to get

149 = 125 x 1 + 24

Step 3: We consider the new divisor 125 and the new remainder 24, and apply the division lemma to get

125 = 24 x 5 + 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 149 and 423 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(24,5) = HCF(125,24) = HCF(149,125) = HCF(423,149) .

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

Step 1: Since 387 > 1, we apply the division lemma to 387 and 1, to get

387 = 1 x 387 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 387 is 1

Notice that 1 = HCF(387,1) .

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

Step 1: Since 539 > 1, we apply the division lemma to 539 and 1, to get

539 = 1 x 539 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 539 is 1

Notice that 1 = HCF(539,1) .
