HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 563, 444 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 563, 444 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 563, 444 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 563, 444 is 1.
HCF(563, 444) = 1
HCF of 563, 444 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 563, 444 is 1.
Highest Common Factor of 563,444 is 1
Step 1: Since 563 > 444, we apply the division lemma to 563 and 444, to get
563 = 444 x 1 + 119
Step 2: Since the reminder 444 ≠ 0, we apply division lemma to 119 and 444, to get
444 = 119 x 3 + 87
Step 3: We consider the new divisor 119 and the new remainder 87, and apply the division lemma to get
119 = 87 x 1 + 32
We consider the new divisor 87 and the new remainder 32,and apply the division lemma to get
87 = 32 x 2 + 23
We consider the new divisor 32 and the new remainder 23,and apply the division lemma to get
32 = 23 x 1 + 9
We consider the new divisor 23 and the new remainder 9,and apply the division lemma to get
23 = 9 x 2 + 5
We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get
9 = 5 x 1 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 563 and 444 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(23,9) = HCF(32,23) = HCF(87,32) = HCF(119,87) = HCF(444,119) = HCF(563,444) .
