HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 520, 724, 101 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 520, 724, 101 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 520, 724, 101 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 520, 724, 101 is 1.
HCF(520, 724, 101) = 1
HCF of 520, 724, 101 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 520, 724, 101 is 1.
Highest Common Factor of 520,724,101 is 1
Step 1: Since 724 > 520, we apply the division lemma to 724 and 520, to get
724 = 520 x 1 + 204
Step 2: Since the reminder 520 ≠ 0, we apply division lemma to 204 and 520, to get
520 = 204 x 2 + 112
Step 3: We consider the new divisor 204 and the new remainder 112, and apply the division lemma to get
204 = 112 x 1 + 92
We consider the new divisor 112 and the new remainder 92,and apply the division lemma to get
112 = 92 x 1 + 20
We consider the new divisor 92 and the new remainder 20,and apply the division lemma to get
92 = 20 x 4 + 12
We consider the new divisor 20 and the new remainder 12,and apply the division lemma to get
20 = 12 x 1 + 8
We consider the new divisor 12 and the new remainder 8,and apply the division lemma to get
12 = 8 x 1 + 4
We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 520 and 724 is 4
Notice that 4 = HCF(8,4) = HCF(12,8) = HCF(20,12) = HCF(92,20) = HCF(112,92) = HCF(204,112) = HCF(520,204) = HCF(724,520) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 101 > 4, we apply the division lemma to 101 and 4, to get
101 = 4 x 25 + 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 101 is 1
Notice that 1 = HCF(4,1) = HCF(101,4) .
