HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 730, 947, 963, 13 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 730, 947, 963, 13 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 730, 947, 963, 13 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 730, 947, 963, 13 is 1.
HCF(730, 947, 963, 13) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 730, 947, 963, 13 is 1.
Step 1: Since 947 > 730, we apply the division lemma to 947 and 730, to get
947 = 730 x 1 + 217
Step 2: Since the reminder 730 ≠ 0, we apply division lemma to 217 and 730, to get
730 = 217 x 3 + 79
Step 3: We consider the new divisor 217 and the new remainder 79, and apply the division lemma to get
217 = 79 x 2 + 59
We consider the new divisor 79 and the new remainder 59,and apply the division lemma to get
79 = 59 x 1 + 20
We consider the new divisor 59 and the new remainder 20,and apply the division lemma to get
59 = 20 x 2 + 19
We consider the new divisor 20 and the new remainder 19,and apply the division lemma to get
20 = 19 x 1 + 1
We consider the new divisor 19 and the new remainder 1,and apply the division lemma to get
19 = 1 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 730 and 947 is 1
Notice that 1 = HCF(19,1) = HCF(20,19) = HCF(59,20) = HCF(79,59) = HCF(217,79) = HCF(730,217) = HCF(947,730) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 963 > 1, we apply the division lemma to 963 and 1, to get
963 = 1 x 963 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 963 is 1
Notice that 1 = HCF(963,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 13 > 1, we apply the division lemma to 13 and 1, to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 13 is 1
Notice that 1 = HCF(13,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
