HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 802, 632 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 802, 632 is 2 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 802, 632 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 802, 632 is 2.
HCF(802, 632) = 2
HCF of 802, 632 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 802, 632 is 2.
Highest Common Factor of 802,632 is 2
Step 1: Since 802 > 632, we apply the division lemma to 802 and 632, to get
802 = 632 x 1 + 170
Step 2: Since the reminder 632 ≠ 0, we apply division lemma to 170 and 632, to get
632 = 170 x 3 + 122
Step 3: We consider the new divisor 170 and the new remainder 122, and apply the division lemma to get
170 = 122 x 1 + 48
We consider the new divisor 122 and the new remainder 48,and apply the division lemma to get
122 = 48 x 2 + 26
We consider the new divisor 48 and the new remainder 26,and apply the division lemma to get
48 = 26 x 1 + 22
We consider the new divisor 26 and the new remainder 22,and apply the division lemma to get
26 = 22 x 1 + 4
We consider the new divisor 22 and the new remainder 4,and apply the division lemma to get
22 = 4 x 5 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 802 and 632 is 2
Notice that 2 = HCF(4,2) = HCF(22,4) = HCF(26,22) = HCF(48,26) = HCF(122,48) = HCF(170,122) = HCF(632,170) = HCF(802,632) .
