HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 216, 788, 290, 904 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 216, 788, 290, 904 is 2 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 216, 788, 290, 904 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 216, 788, 290, 904 is 2.
HCF(216, 788, 290, 904) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 216, 788, 290, 904 is 2.
Step 1: Since 788 > 216, we apply the division lemma to 788 and 216, to get
788 = 216 x 3 + 140
Step 2: Since the reminder 216 ≠ 0, we apply division lemma to 140 and 216, to get
216 = 140 x 1 + 76
Step 3: We consider the new divisor 140 and the new remainder 76, and apply the division lemma to get
140 = 76 x 1 + 64
We consider the new divisor 76 and the new remainder 64,and apply the division lemma to get
76 = 64 x 1 + 12
We consider the new divisor 64 and the new remainder 12,and apply the division lemma to get
64 = 12 x 5 + 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 216 and 788 is 4
Notice that 4 = HCF(12,4) = HCF(64,12) = HCF(76,64) = HCF(140,76) = HCF(216,140) = HCF(788,216) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 290 > 4, we apply the division lemma to 290 and 4, to get
290 = 4 x 72 + 2
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 2 and 4, to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 4 and 290 is 2
Notice that 2 = HCF(4,2) = HCF(290,4) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 904 > 2, we apply the division lemma to 904 and 2, to get
904 = 2 x 452 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 904 is 2
Notice that 2 = HCF(904,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
