HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 530, 470, 385 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 530, 470, 385 is 5 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 530, 470, 385 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 530, 470, 385 is 5.
HCF(530, 470, 385) = 5
HCF of 530, 470, 385 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 530, 470, 385 is 5.
Highest Common Factor of 530,470,385 is 5
Step 1: Since 530 > 470, we apply the division lemma to 530 and 470, to get
530 = 470 x 1 + 60
Step 2: Since the reminder 470 ≠ 0, we apply division lemma to 60 and 470, to get
470 = 60 x 7 + 50
Step 3: We consider the new divisor 60 and the new remainder 50, and apply the division lemma to get
60 = 50 x 1 + 10
We consider the new divisor 50 and the new remainder 10, and apply the division lemma to get
50 = 10 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 530 and 470 is 10
Notice that 10 = HCF(50,10) = HCF(60,50) = HCF(470,60) = HCF(530,470) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 385 > 10, we apply the division lemma to 385 and 10, to get
385 = 10 x 38 + 5
Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 5 and 10, to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 10 and 385 is 5
Notice that 5 = HCF(10,5) = HCF(385,10) .
