HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 620, 712, 949, 29 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 620, 712, 949, 29 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 620, 712, 949, 29 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 620, 712, 949, 29 is 1.
HCF(620, 712, 949, 29) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 620, 712, 949, 29 is 1.
Step 1: Since 712 > 620, we apply the division lemma to 712 and 620, to get
712 = 620 x 1 + 92
Step 2: Since the reminder 620 ≠ 0, we apply division lemma to 92 and 620, to get
620 = 92 x 6 + 68
Step 3: We consider the new divisor 92 and the new remainder 68, and apply the division lemma to get
92 = 68 x 1 + 24
We consider the new divisor 68 and the new remainder 24,and apply the division lemma to get
68 = 24 x 2 + 20
We consider the new divisor 24 and the new remainder 20,and apply the division lemma to get
24 = 20 x 1 + 4
We consider the new divisor 20 and the new remainder 4,and apply the division lemma to get
20 = 4 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 620 and 712 is 4
Notice that 4 = HCF(20,4) = HCF(24,20) = HCF(68,24) = HCF(92,68) = HCF(620,92) = HCF(712,620) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 949 > 4, we apply the division lemma to 949 and 4, to get
949 = 4 x 237 + 1
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 949 is 1
Notice that 1 = HCF(4,1) = HCF(949,4) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 29 > 1, we apply the division lemma to 29 and 1, to get
29 = 1 x 29 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 29 is 1
Notice that 1 = HCF(29,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
