HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 656, 840, 299, 213 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 656, 840, 299, 213 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 656, 840, 299, 213 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 656, 840, 299, 213 is 1.
HCF(656, 840, 299, 213) = 1
HCF of 656, 840, 299, 213 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 656, 840, 299, 213 is 1.
Highest Common Factor of 656,840,299,213 is 1
Step 1: Since 840 > 656, we apply the division lemma to 840 and 656, to get
840 = 656 x 1 + 184
Step 2: Since the reminder 656 ≠ 0, we apply division lemma to 184 and 656, to get
656 = 184 x 3 + 104
Step 3: We consider the new divisor 184 and the new remainder 104, and apply the division lemma to get
184 = 104 x 1 + 80
We consider the new divisor 104 and the new remainder 80,and apply the division lemma to get
104 = 80 x 1 + 24
We consider the new divisor 80 and the new remainder 24,and apply the division lemma to get
80 = 24 x 3 + 8
We consider the new divisor 24 and the new remainder 8,and apply the division lemma to get
24 = 8 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 8, the HCF of 656 and 840 is 8
Notice that 8 = HCF(24,8) = HCF(80,24) = HCF(104,80) = HCF(184,104) = HCF(656,184) = HCF(840,656) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 299 > 8, we apply the division lemma to 299 and 8, to get
299 = 8 x 37 + 3
Step 2: Since the reminder 8 ≠ 0, we apply division lemma to 3 and 8, to get
8 = 3 x 2 + 2
Step 3: We consider the new divisor 3 and the new remainder 2, and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 8 and 299 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(299,8) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 213 > 1, we apply the division lemma to 213 and 1, to get
213 = 1 x 213 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 213 is 1
Notice that 1 = HCF(213,1) .
