HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 646, 795, 407 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 646, 795, 407 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 646, 795, 407 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 646, 795, 407 is 1.
HCF(646, 795, 407) = 1
HCF of 646, 795, 407 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 646, 795, 407 is 1.
Highest Common Factor of 646,795,407 is 1
Step 1: Since 795 > 646, we apply the division lemma to 795 and 646, to get
795 = 646 x 1 + 149
Step 2: Since the reminder 646 ≠ 0, we apply division lemma to 149 and 646, to get
646 = 149 x 4 + 50
Step 3: We consider the new divisor 149 and the new remainder 50, and apply the division lemma to get
149 = 50 x 2 + 49
We consider the new divisor 50 and the new remainder 49,and apply the division lemma to get
50 = 49 x 1 + 1
We consider the new divisor 49 and the new remainder 1,and apply the division lemma to get
49 = 1 x 49 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 646 and 795 is 1
Notice that 1 = HCF(49,1) = HCF(50,49) = HCF(149,50) = HCF(646,149) = HCF(795,646) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 407 > 1, we apply the division lemma to 407 and 1, to get
407 = 1 x 407 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 407 is 1
Notice that 1 = HCF(407,1) .
