HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 715, 643, 346 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 715, 643, 346 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 715, 643, 346 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 715, 643, 346 is 1.
HCF(715, 643, 346) = 1
HCF of 715, 643, 346 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 715, 643, 346 is 1.
Highest Common Factor of 715,643,346 is 1
Step 1: Since 715 > 643, we apply the division lemma to 715 and 643, to get
715 = 643 x 1 + 72
Step 2: Since the reminder 643 ≠ 0, we apply division lemma to 72 and 643, to get
643 = 72 x 8 + 67
Step 3: We consider the new divisor 72 and the new remainder 67, and apply the division lemma to get
72 = 67 x 1 + 5
We consider the new divisor 67 and the new remainder 5,and apply the division lemma to get
67 = 5 x 13 + 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 715 and 643 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(67,5) = HCF(72,67) = HCF(643,72) = HCF(715,643) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 346 > 1, we apply the division lemma to 346 and 1, to get
346 = 1 x 346 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 346 is 1
Notice that 1 = HCF(346,1) .
