HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 665, 917, 433, 563 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 665, 917, 433, 563 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 665, 917, 433, 563 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 665, 917, 433, 563 is 1.
HCF(665, 917, 433, 563) = 1
HCF of 665, 917, 433, 563 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 665, 917, 433, 563 is 1.
Highest Common Factor of 665,917,433,563 is 1
Step 1: Since 917 > 665, we apply the division lemma to 917 and 665, to get
917 = 665 x 1 + 252
Step 2: Since the reminder 665 ≠ 0, we apply division lemma to 252 and 665, to get
665 = 252 x 2 + 161
Step 3: We consider the new divisor 252 and the new remainder 161, and apply the division lemma to get
252 = 161 x 1 + 91
We consider the new divisor 161 and the new remainder 91,and apply the division lemma to get
161 = 91 x 1 + 70
We consider the new divisor 91 and the new remainder 70,and apply the division lemma to get
91 = 70 x 1 + 21
We consider the new divisor 70 and the new remainder 21,and apply the division lemma to get
70 = 21 x 3 + 7
We consider the new divisor 21 and the new remainder 7,and apply the division lemma to get
21 = 7 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 665 and 917 is 7
Notice that 7 = HCF(21,7) = HCF(70,21) = HCF(91,70) = HCF(161,91) = HCF(252,161) = HCF(665,252) = HCF(917,665) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 433 > 7, we apply the division lemma to 433 and 7, to get
433 = 7 x 61 + 6
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 6 and 7, to get
7 = 6 x 1 + 1
Step 3: We consider the new divisor 6 and the new remainder 1, and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7 and 433 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(433,7) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 563 > 1, we apply the division lemma to 563 and 1, to get
563 = 1 x 563 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 563 is 1
Notice that 1 = HCF(563,1) .
