HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 534, 945, 459, 25 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 534, 945, 459, 25 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 534, 945, 459, 25 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 534, 945, 459, 25 is 1.
HCF(534, 945, 459, 25) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 534, 945, 459, 25 is 1.
Step 1: Since 945 > 534, we apply the division lemma to 945 and 534, to get
945 = 534 x 1 + 411
Step 2: Since the reminder 534 ≠ 0, we apply division lemma to 411 and 534, to get
534 = 411 x 1 + 123
Step 3: We consider the new divisor 411 and the new remainder 123, and apply the division lemma to get
411 = 123 x 3 + 42
We consider the new divisor 123 and the new remainder 42,and apply the division lemma to get
123 = 42 x 2 + 39
We consider the new divisor 42 and the new remainder 39,and apply the division lemma to get
42 = 39 x 1 + 3
We consider the new divisor 39 and the new remainder 3,and apply the division lemma to get
39 = 3 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 534 and 945 is 3
Notice that 3 = HCF(39,3) = HCF(42,39) = HCF(123,42) = HCF(411,123) = HCF(534,411) = HCF(945,534) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 459 > 3, we apply the division lemma to 459 and 3, to get
459 = 3 x 153 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 459 is 3
Notice that 3 = HCF(459,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 25 > 3, we apply the division lemma to 25 and 3, to get
25 = 3 x 8 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 25 is 1
Notice that 1 = HCF(3,1) = HCF(25,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.
