HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 822, 4755 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 822, 4755 is 3 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 822, 4755 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 822, 4755 is 3.
HCF(822, 4755) = 3
HCF of 822, 4755 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 822, 4755 is 3.
Highest Common Factor of 822,4755 is 3
Step 1: Since 4755 > 822, we apply the division lemma to 4755 and 822, to get
4755 = 822 x 5 + 645
Step 2: Since the reminder 822 ≠ 0, we apply division lemma to 645 and 822, to get
822 = 645 x 1 + 177
Step 3: We consider the new divisor 645 and the new remainder 177, and apply the division lemma to get
645 = 177 x 3 + 114
We consider the new divisor 177 and the new remainder 114,and apply the division lemma to get
177 = 114 x 1 + 63
We consider the new divisor 114 and the new remainder 63,and apply the division lemma to get
114 = 63 x 1 + 51
We consider the new divisor 63 and the new remainder 51,and apply the division lemma to get
63 = 51 x 1 + 12
We consider the new divisor 51 and the new remainder 12,and apply the division lemma to get
51 = 12 x 4 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 822 and 4755 is 3
Notice that 3 = HCF(12,3) = HCF(51,12) = HCF(63,51) = HCF(114,63) = HCF(177,114) = HCF(645,177) = HCF(822,645) = HCF(4755,822) .
