HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 822, 928, 223, 457 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 822, 928, 223, 457 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 822, 928, 223, 457 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 822, 928, 223, 457 is 1.
HCF(822, 928, 223, 457) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 822, 928, 223, 457 is 1.
Step 1: Since 928 > 822, we apply the division lemma to 928 and 822, to get
928 = 822 x 1 + 106
Step 2: Since the reminder 822 ≠ 0, we apply division lemma to 106 and 822, to get
822 = 106 x 7 + 80
Step 3: We consider the new divisor 106 and the new remainder 80, and apply the division lemma to get
106 = 80 x 1 + 26
We consider the new divisor 80 and the new remainder 26,and apply the division lemma to get
80 = 26 x 3 + 2
We consider the new divisor 26 and the new remainder 2,and apply the division lemma to get
26 = 2 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 822 and 928 is 2
Notice that 2 = HCF(26,2) = HCF(80,26) = HCF(106,80) = HCF(822,106) = HCF(928,822) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 223 > 2, we apply the division lemma to 223 and 2, to get
223 = 2 x 111 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 223 is 1
Notice that 1 = HCF(2,1) = HCF(223,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 457 > 1, we apply the division lemma to 457 and 1, to get
457 = 1 x 457 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 457 is 1
Notice that 1 = HCF(457,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
