HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 804, 419, 74 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 804, 419, 74 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 804, 419, 74 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 804, 419, 74 is 1.
HCF(804, 419, 74) = 1
HCF of 804, 419, 74 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 804, 419, 74 is 1.
Highest Common Factor of 804,419,74 is 1
Step 1: Since 804 > 419, we apply the division lemma to 804 and 419, to get
804 = 419 x 1 + 385
Step 2: Since the reminder 419 ≠ 0, we apply division lemma to 385 and 419, to get
419 = 385 x 1 + 34
Step 3: We consider the new divisor 385 and the new remainder 34, and apply the division lemma to get
385 = 34 x 11 + 11
We consider the new divisor 34 and the new remainder 11,and apply the division lemma to get
34 = 11 x 3 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 804 and 419 is 1
Notice that 1 = HCF(11,1) = HCF(34,11) = HCF(385,34) = HCF(419,385) = HCF(804,419) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 74 > 1, we apply the division lemma to 74 and 1, to get
74 = 1 x 74 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 74 is 1
Notice that 1 = HCF(74,1) .
