HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 768, 223, 530, 763 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 768, 223, 530, 763 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 768, 223, 530, 763 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 768, 223, 530, 763 is 1.
HCF(768, 223, 530, 763) = 1
HCF of 768, 223, 530, 763 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 768, 223, 530, 763 is 1.
Highest Common Factor of 768,223,530,763 is 1
Step 1: Since 768 > 223, we apply the division lemma to 768 and 223, to get
768 = 223 x 3 + 99
Step 2: Since the reminder 223 ≠ 0, we apply division lemma to 99 and 223, to get
223 = 99 x 2 + 25
Step 3: We consider the new divisor 99 and the new remainder 25, and apply the division lemma to get
99 = 25 x 3 + 24
We consider the new divisor 25 and the new remainder 24,and apply the division lemma to get
25 = 24 x 1 + 1
We consider the new divisor 24 and the new remainder 1,and apply the division lemma to get
24 = 1 x 24 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 768 and 223 is 1
Notice that 1 = HCF(24,1) = HCF(25,24) = HCF(99,25) = HCF(223,99) = HCF(768,223) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 530 > 1, we apply the division lemma to 530 and 1, to get
530 = 1 x 530 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 530 is 1
Notice that 1 = HCF(530,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 763 > 1, we apply the division lemma to 763 and 1, to get
763 = 1 x 763 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 763 is 1
Notice that 1 = HCF(763,1) .
