HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 804, 440 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 804, 440 is 4 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, 440 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, 440 is 4.
HCF(804, 440) = 4
HCF of 804, 440 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, 440 is 4.
Highest Common Factor of 804,440 is 4
Step 1: Since 804 > 440, we apply the division lemma to 804 and 440, to get
804 = 440 x 1 + 364
Step 2: Since the reminder 440 ≠ 0, we apply division lemma to 364 and 440, to get
440 = 364 x 1 + 76
Step 3: We consider the new divisor 364 and the new remainder 76, and apply the division lemma to get
364 = 76 x 4 + 60
We consider the new divisor 76 and the new remainder 60,and apply the division lemma to get
76 = 60 x 1 + 16
We consider the new divisor 60 and the new remainder 16,and apply the division lemma to get
60 = 16 x 3 + 12
We consider the new divisor 16 and the new remainder 12,and apply the division lemma to get
16 = 12 x 1 + 4
We consider the new divisor 12 and the new remainder 4,and apply the division lemma to get
12 = 4 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 804 and 440 is 4
Notice that 4 = HCF(12,4) = HCF(16,12) = HCF(60,16) = HCF(76,60) = HCF(364,76) = HCF(440,364) = HCF(804,440) .
