HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 320, 530, 977 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 320, 530, 977 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 320, 530, 977 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 320, 530, 977 is 1.
HCF(320, 530, 977) = 1
HCF of 320, 530, 977 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 320, 530, 977 is 1.
Highest Common Factor of 320,530,977 is 1
Step 1: Since 530 > 320, we apply the division lemma to 530 and 320, to get
530 = 320 x 1 + 210
Step 2: Since the reminder 320 ≠ 0, we apply division lemma to 210 and 320, to get
320 = 210 x 1 + 110
Step 3: We consider the new divisor 210 and the new remainder 110, and apply the division lemma to get
210 = 110 x 1 + 100
We consider the new divisor 110 and the new remainder 100,and apply the division lemma to get
110 = 100 x 1 + 10
We consider the new divisor 100 and the new remainder 10,and apply the division lemma to get
100 = 10 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 320 and 530 is 10
Notice that 10 = HCF(100,10) = HCF(110,100) = HCF(210,110) = HCF(320,210) = HCF(530,320) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 977 > 10, we apply the division lemma to 977 and 10, to get
977 = 10 x 97 + 7
Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 7 and 10, to get
10 = 7 x 1 + 3
Step 3: We consider the new divisor 7 and the new remainder 3, and apply the division lemma to get
7 = 3 x 2 + 1
We consider the new divisor 3 and the new remainder 1, and apply the division lemma 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 10 and 977 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(977,10) .
