HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 902, 771 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 902, 771 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 902, 771 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 902, 771 is 1.
HCF(902, 771) = 1
HCF of 902, 771 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 902, 771 is 1.
Highest Common Factor of 902,771 is 1
Step 1: Since 902 > 771, we apply the division lemma to 902 and 771, to get
902 = 771 x 1 + 131
Step 2: Since the reminder 771 ≠ 0, we apply division lemma to 131 and 771, to get
771 = 131 x 5 + 116
Step 3: We consider the new divisor 131 and the new remainder 116, and apply the division lemma to get
131 = 116 x 1 + 15
We consider the new divisor 116 and the new remainder 15,and apply the division lemma to get
116 = 15 x 7 + 11
We consider the new divisor 15 and the new remainder 11,and apply the division lemma to get
15 = 11 x 1 + 4
We consider the new divisor 11 and the new remainder 4,and apply the division lemma to get
11 = 4 x 2 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 902 and 771 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(15,11) = HCF(116,15) = HCF(131,116) = HCF(771,131) = HCF(902,771) .
