HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 570, 149, 224, 203 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 570, 149, 224, 203 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 570, 149, 224, 203 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 570, 149, 224, 203 is 1.

HCF(570, 149, 224, 203) = 1

Highest Common Factor of 570,149,224,203 using Euclid's algorithm

Highest Common Factor of 570,149,224,203 is 1

Step 1: Since 570 > 149, we apply the division lemma to 570 and 149, to get

570 = 149 x 3 + 123

Step 2: Since the reminder 149 ≠ 0, we apply division lemma to 123 and 149, to get

149 = 123 x 1 + 26

Step 3: We consider the new divisor 123 and the new remainder 26, and apply the division lemma to get

123 = 26 x 4 + 19

We consider the new divisor 26 and the new remainder 19,and apply the division lemma to get

26 = 19 x 1 + 7

We consider the new divisor 19 and the new remainder 7,and apply the division lemma to get

19 = 7 x 2 + 5

We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get

7 = 5 x 1 + 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 570 and 149 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(19,7) = HCF(26,19) = HCF(123,26) = HCF(149,123) = HCF(570,149) .


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

Step 1: Since 224 > 1, we apply the division lemma to 224 and 1, to get

224 = 1 x 224 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 224 is 1

Notice that 1 = HCF(224,1) .


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

Step 1: Since 203 > 1, we apply the division lemma to 203 and 1, to get

203 = 1 x 203 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 203 is 1

Notice that 1 = HCF(203,1) .
