HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 443, 910, 771, 722 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 443, 910, 771, 722 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 443, 910, 771, 722 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 443, 910, 771, 722 is 1.
HCF(443, 910, 771, 722) = 1
HCF of 443, 910, 771, 722 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 443, 910, 771, 722 is 1.
Highest Common Factor of 443,910,771,722 is 1
Step 1: Since 910 > 443, we apply the division lemma to 910 and 443, to get
910 = 443 x 2 + 24
Step 2: Since the reminder 443 ≠ 0, we apply division lemma to 24 and 443, to get
443 = 24 x 18 + 11
Step 3: We consider the new divisor 24 and the new remainder 11, and apply the division lemma to get
24 = 11 x 2 + 2
We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get
11 = 2 x 5 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 443 and 910 is 1
Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(24,11) = HCF(443,24) = HCF(910,443) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 771 > 1, we apply the division lemma to 771 and 1, to get
771 = 1 x 771 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 771 is 1
Notice that 1 = HCF(771,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 722 > 1, we apply the division lemma to 722 and 1, to get
722 = 1 x 722 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 722 is 1
Notice that 1 = HCF(722,1) .
