HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 963, 730, 646 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 963, 730, 646 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 963, 730, 646 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 963, 730, 646 is 1.
HCF(963, 730, 646) = 1
HCF of 963, 730, 646 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 963, 730, 646 is 1.
Highest Common Factor of 963,730,646 is 1
Step 1: Since 963 > 730, we apply the division lemma to 963 and 730, to get
963 = 730 x 1 + 233
Step 2: Since the reminder 730 ≠ 0, we apply division lemma to 233 and 730, to get
730 = 233 x 3 + 31
Step 3: We consider the new divisor 233 and the new remainder 31, and apply the division lemma to get
233 = 31 x 7 + 16
We consider the new divisor 31 and the new remainder 16,and apply the division lemma to get
31 = 16 x 1 + 15
We consider the new divisor 16 and the new remainder 15,and apply the division lemma to get
16 = 15 x 1 + 1
We consider the new divisor 15 and the new remainder 1,and apply the division lemma to get
15 = 1 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 963 and 730 is 1
Notice that 1 = HCF(15,1) = HCF(16,15) = HCF(31,16) = HCF(233,31) = HCF(730,233) = HCF(963,730) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 646 > 1, we apply the division lemma to 646 and 1, to get
646 = 1 x 646 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 646 is 1
Notice that 1 = HCF(646,1) .
