HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 718, 408, 22 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 718, 408, 22 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 718, 408, 22 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 718, 408, 22 is 2.
HCF(718, 408, 22) = 2
HCF of 718, 408, 22 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 718, 408, 22 is 2.
Highest Common Factor of 718,408,22 is 2
Step 1: Since 718 > 408, we apply the division lemma to 718 and 408, to get
718 = 408 x 1 + 310
Step 2: Since the reminder 408 ≠ 0, we apply division lemma to 310 and 408, to get
408 = 310 x 1 + 98
Step 3: We consider the new divisor 310 and the new remainder 98, and apply the division lemma to get
310 = 98 x 3 + 16
We consider the new divisor 98 and the new remainder 16,and apply the division lemma to get
98 = 16 x 6 + 2
We consider the new divisor 16 and the new remainder 2,and apply the division lemma to get
16 = 2 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 718 and 408 is 2
Notice that 2 = HCF(16,2) = HCF(98,16) = HCF(310,98) = HCF(408,310) = HCF(718,408) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 22 > 2, we apply the division lemma to 22 and 2, to get
22 = 2 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 22 is 2
Notice that 2 = HCF(22,2) .
