HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 407, 418, 851 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 407, 418, 851 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 407, 418, 851 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 407, 418, 851 is 1.
HCF(407, 418, 851) = 1
HCF of 407, 418, 851 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 407, 418, 851 is 1.
Highest Common Factor of 407,418,851 is 1
Step 1: Since 418 > 407, we apply the division lemma to 418 and 407, to get
418 = 407 x 1 + 11
Step 2: Since the reminder 407 ≠ 0, we apply division lemma to 11 and 407, to get
407 = 11 x 37 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 407 and 418 is 11
Notice that 11 = HCF(407,11) = HCF(418,407) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 851 > 11, we apply the division lemma to 851 and 11, to get
851 = 11 x 77 + 4
Step 2: Since the reminder 11 ≠ 0, we apply division lemma to 4 and 11, to get
11 = 4 x 2 + 3
Step 3: We consider the new divisor 4 and the new remainder 3, and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 11 and 851 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(851,11) .
