HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 417, 406, 777 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 417, 406, 777 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 417, 406, 777 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 417, 406, 777 is 1.
HCF(417, 406, 777) = 1
HCF of 417, 406, 777 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 417, 406, 777 is 1.
Highest Common Factor of 417,406,777 is 1
Step 1: Since 417 > 406, we apply the division lemma to 417 and 406, to get
417 = 406 x 1 + 11
Step 2: Since the reminder 406 ≠ 0, we apply division lemma to 11 and 406, to get
406 = 11 x 36 + 10
Step 3: We consider the new divisor 11 and the new remainder 10, and apply the division lemma to get
11 = 10 x 1 + 1
We consider the new divisor 10 and the new remainder 1, and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 417 and 406 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(406,11) = HCF(417,406) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 777 > 1, we apply the division lemma to 777 and 1, to get
777 = 1 x 777 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 777 is 1
Notice that 1 = HCF(777,1) .
