HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 616, 420, 804 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 616, 420, 804 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 616, 420, 804 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 616, 420, 804 is 4.
HCF(616, 420, 804) = 4
HCF of 616, 420, 804 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 616, 420, 804 is 4.
Highest Common Factor of 616,420,804 is 4
Step 1: Since 616 > 420, we apply the division lemma to 616 and 420, to get
616 = 420 x 1 + 196
Step 2: Since the reminder 420 ≠ 0, we apply division lemma to 196 and 420, to get
420 = 196 x 2 + 28
Step 3: We consider the new divisor 196 and the new remainder 28, and apply the division lemma to get
196 = 28 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 28, the HCF of 616 and 420 is 28
Notice that 28 = HCF(196,28) = HCF(420,196) = HCF(616,420) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 804 > 28, we apply the division lemma to 804 and 28, to get
804 = 28 x 28 + 20
Step 2: Since the reminder 28 ≠ 0, we apply division lemma to 20 and 28, to get
28 = 20 x 1 + 8
Step 3: We consider the new divisor 20 and the new remainder 8, and apply the division lemma to get
20 = 8 x 2 + 4
We consider the new divisor 8 and the new remainder 4, and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 28 and 804 is 4
Notice that 4 = HCF(8,4) = HCF(20,8) = HCF(28,20) = HCF(804,28) .
