HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 748, 462, 891 i.e. 11 the largest integer that leaves a remainder zero for all numbers.
HCF of 748, 462, 891 is 11 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 748, 462, 891 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 748, 462, 891 is 11.
HCF(748, 462, 891) = 11
HCF of 748, 462, 891 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 748, 462, 891 is 11.
Highest Common Factor of 748,462,891 is 11
Step 1: Since 748 > 462, we apply the division lemma to 748 and 462, to get
748 = 462 x 1 + 286
Step 2: Since the reminder 462 ≠ 0, we apply division lemma to 286 and 462, to get
462 = 286 x 1 + 176
Step 3: We consider the new divisor 286 and the new remainder 176, and apply the division lemma to get
286 = 176 x 1 + 110
We consider the new divisor 176 and the new remainder 110,and apply the division lemma to get
176 = 110 x 1 + 66
We consider the new divisor 110 and the new remainder 66,and apply the division lemma to get
110 = 66 x 1 + 44
We consider the new divisor 66 and the new remainder 44,and apply the division lemma to get
66 = 44 x 1 + 22
We consider the new divisor 44 and the new remainder 22,and apply the division lemma to get
44 = 22 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 22, the HCF of 748 and 462 is 22
Notice that 22 = HCF(44,22) = HCF(66,44) = HCF(110,66) = HCF(176,110) = HCF(286,176) = HCF(462,286) = HCF(748,462) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 891 > 22, we apply the division lemma to 891 and 22, to get
891 = 22 x 40 + 11
Step 2: Since the reminder 22 ≠ 0, we apply division lemma to 11 and 22, to get
22 = 11 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 22 and 891 is 11
Notice that 11 = HCF(22,11) = HCF(891,22) .
