HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 147, 389, 944, 431 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 147, 389, 944, 431 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 147, 389, 944, 431 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 147, 389, 944, 431 is 1.
HCF(147, 389, 944, 431) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 147, 389, 944, 431 is 1.
Step 1: Since 389 > 147, we apply the division lemma to 389 and 147, to get
389 = 147 x 2 + 95
Step 2: Since the reminder 147 ≠ 0, we apply division lemma to 95 and 147, to get
147 = 95 x 1 + 52
Step 3: We consider the new divisor 95 and the new remainder 52, and apply the division lemma to get
95 = 52 x 1 + 43
We consider the new divisor 52 and the new remainder 43,and apply the division lemma to get
52 = 43 x 1 + 9
We consider the new divisor 43 and the new remainder 9,and apply the division lemma to get
43 = 9 x 4 + 7
We consider the new divisor 9 and the new remainder 7,and apply the division lemma to get
9 = 7 x 1 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 147 and 389 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(43,9) = HCF(52,43) = HCF(95,52) = HCF(147,95) = HCF(389,147) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 944 > 1, we apply the division lemma to 944 and 1, to get
944 = 1 x 944 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 944 is 1
Notice that 1 = HCF(944,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 431 > 1, we apply the division lemma to 431 and 1, to get
431 = 1 x 431 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 431 is 1
Notice that 1 = HCF(431,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
