HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 630, 251, 477, 931 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 630, 251, 477, 931 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 630, 251, 477, 931 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 630, 251, 477, 931 is 1.
HCF(630, 251, 477, 931) = 1
HCF of 630, 251, 477, 931 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 630, 251, 477, 931 is 1.
Highest Common Factor of 630,251,477,931 is 1
Step 1: Since 630 > 251, we apply the division lemma to 630 and 251, to get
630 = 251 x 2 + 128
Step 2: Since the reminder 251 ≠ 0, we apply division lemma to 128 and 251, to get
251 = 128 x 1 + 123
Step 3: We consider the new divisor 128 and the new remainder 123, and apply the division lemma to get
128 = 123 x 1 + 5
We consider the new divisor 123 and the new remainder 5,and apply the division lemma to get
123 = 5 x 24 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 630 and 251 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(123,5) = HCF(128,123) = HCF(251,128) = HCF(630,251) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 477 > 1, we apply the division lemma to 477 and 1, to get
477 = 1 x 477 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 477 is 1
Notice that 1 = HCF(477,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 931 > 1, we apply the division lemma to 931 and 1, to get
931 = 1 x 931 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 931 is 1
Notice that 1 = HCF(931,1) .
