HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 431, 198, 573, 255 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 431, 198, 573, 255 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 431, 198, 573, 255 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 431, 198, 573, 255 is 1.

HCF(431, 198, 573, 255) = 1

Highest common factor (HCF) of 431, 198, 573, 255 is 1.

Highest Common Factor of 431,198,573,255 using Euclid's algorithm

Highest Common Factor of 431,198,573,255 is 1

Step 1: Since 431 > 198, we apply the division lemma to 431 and 198, to get

431 = 198 x 2 + 35

Step 2: Since the reminder 198 ≠ 0, we apply division lemma to 35 and 198, to get

198 = 35 x 5 + 23

Step 3: We consider the new divisor 35 and the new remainder 23, and apply the division lemma to get

35 = 23 x 1 + 12

We consider the new divisor 23 and the new remainder 12,and apply the division lemma to get

23 = 12 x 1 + 11

We consider the new divisor 12 and the new remainder 11,and apply the division lemma to get

12 = 11 x 1 + 1

We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get

11 = 1 x 11 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 431 and 198 is 1

Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(23,12) = HCF(35,23) = HCF(198,35) = HCF(431,198) .


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

Step 1: Since 573 > 1, we apply the division lemma to 573 and 1, to get

573 = 1 x 573 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 573 is 1

Notice that 1 = HCF(573,1) .


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

Step 1: Since 255 > 1, we apply the division lemma to 255 and 1, to get

255 = 1 x 255 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 255 is 1

Notice that 1 = HCF(255,1) .
