HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 664, 126, 621, 933 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 664, 126, 621, 933 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 664, 126, 621, 933 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 664, 126, 621, 933 is 1.
HCF(664, 126, 621, 933) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 664, 126, 621, 933 is 1.
Step 1: Since 664 > 126, we apply the division lemma to 664 and 126, to get
664 = 126 x 5 + 34
Step 2: Since the reminder 126 ≠ 0, we apply division lemma to 34 and 126, to get
126 = 34 x 3 + 24
Step 3: We consider the new divisor 34 and the new remainder 24, and apply the division lemma to get
34 = 24 x 1 + 10
We consider the new divisor 24 and the new remainder 10,and apply the division lemma to get
24 = 10 x 2 + 4
We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get
10 = 4 x 2 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 664 and 126 is 2
Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(24,10) = HCF(34,24) = HCF(126,34) = HCF(664,126) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 621 > 2, we apply the division lemma to 621 and 2, to get
621 = 2 x 310 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 621 is 1
Notice that 1 = HCF(2,1) = HCF(621,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 933 > 1, we apply the division lemma to 933 and 1, to get
933 = 1 x 933 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 933 is 1
Notice that 1 = HCF(933,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
