HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 22, 81, 302, 708 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 22, 81, 302, 708 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 22, 81, 302, 708 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 22, 81, 302, 708 is 1.
HCF(22, 81, 302, 708) = 1
HCF of 22, 81, 302, 708 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 22, 81, 302, 708 is 1.
Highest Common Factor of 22,81,302,708 is 1
Step 1: Since 81 > 22, we apply the division lemma to 81 and 22, to get
81 = 22 x 3 + 15
Step 2: Since the reminder 22 ≠ 0, we apply division lemma to 15 and 22, to get
22 = 15 x 1 + 7
Step 3: We consider the new divisor 15 and the new remainder 7, and apply the division lemma to get
15 = 7 x 2 + 1
We consider the new divisor 7 and the new remainder 1, and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 22 and 81 is 1
Notice that 1 = HCF(7,1) = HCF(15,7) = HCF(22,15) = HCF(81,22) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 302 > 1, we apply the division lemma to 302 and 1, to get
302 = 1 x 302 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 302 is 1
Notice that 1 = HCF(302,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 708 > 1, we apply the division lemma to 708 and 1, to get
708 = 1 x 708 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 708 is 1
Notice that 1 = HCF(708,1) .
