HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 189, 791, 431, 630 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 189, 791, 431, 630 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 189, 791, 431, 630 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 189, 791, 431, 630 is 1.
HCF(189, 791, 431, 630) = 1
HCF of 189, 791, 431, 630 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 189, 791, 431, 630 is 1.
Highest Common Factor of 189,791,431,630 is 1
Step 1: Since 791 > 189, we apply the division lemma to 791 and 189, to get
791 = 189 x 4 + 35
Step 2: Since the reminder 189 ≠ 0, we apply division lemma to 35 and 189, to get
189 = 35 x 5 + 14
Step 3: We consider the new divisor 35 and the new remainder 14, and apply the division lemma to get
35 = 14 x 2 + 7
We consider the new divisor 14 and the new remainder 7, and apply the division lemma to get
14 = 7 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 189 and 791 is 7
Notice that 7 = HCF(14,7) = HCF(35,14) = HCF(189,35) = HCF(791,189) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 431 > 7, we apply the division lemma to 431 and 7, to get
431 = 7 x 61 + 4
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 4 and 7, to get
7 = 4 x 1 + 3
Step 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 7 and 431 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(431,7) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 630 > 1, we apply the division lemma to 630 and 1, to get
630 = 1 x 630 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 630 is 1
Notice that 1 = HCF(630,1) .
