HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 745, 646, 386 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 745, 646, 386 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 745, 646, 386 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 745, 646, 386 is 1.
HCF(745, 646, 386) = 1
HCF of 745, 646, 386 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 745, 646, 386 is 1.
Highest Common Factor of 745,646,386 is 1
Step 1: Since 745 > 646, we apply the division lemma to 745 and 646, to get
745 = 646 x 1 + 99
Step 2: Since the reminder 646 ≠ 0, we apply division lemma to 99 and 646, to get
646 = 99 x 6 + 52
Step 3: We consider the new divisor 99 and the new remainder 52, and apply the division lemma to get
99 = 52 x 1 + 47
We consider the new divisor 52 and the new remainder 47,and apply the division lemma to get
52 = 47 x 1 + 5
We consider the new divisor 47 and the new remainder 5,and apply the division lemma to get
47 = 5 x 9 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 745 and 646 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(47,5) = HCF(52,47) = HCF(99,52) = HCF(646,99) = HCF(745,646) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 386 > 1, we apply the division lemma to 386 and 1, to get
386 = 1 x 386 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 386 is 1
Notice that 1 = HCF(386,1) .
