HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 577, 381, 439, 963 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 577, 381, 439, 963 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 577, 381, 439, 963 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 577, 381, 439, 963 is 1.
HCF(577, 381, 439, 963) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 577, 381, 439, 963 is 1.
Step 1: Since 577 > 381, we apply the division lemma to 577 and 381, to get
577 = 381 x 1 + 196
Step 2: Since the reminder 381 ≠ 0, we apply division lemma to 196 and 381, to get
381 = 196 x 1 + 185
Step 3: We consider the new divisor 196 and the new remainder 185, and apply the division lemma to get
196 = 185 x 1 + 11
We consider the new divisor 185 and the new remainder 11,and apply the division lemma to get
185 = 11 x 16 + 9
We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get
11 = 9 x 1 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 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 577 and 381 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(185,11) = HCF(196,185) = HCF(381,196) = HCF(577,381) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 439 > 1, we apply the division lemma to 439 and 1, to get
439 = 1 x 439 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 439 is 1
Notice that 1 = HCF(439,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 963 > 1, we apply the division lemma to 963 and 1, to get
963 = 1 x 963 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 963 is 1
Notice that 1 = HCF(963,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
