HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 523, 902 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 523, 902 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 523, 902 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 523, 902 is 1.
HCF(523, 902) = 1
HCF of 523, 902 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 523, 902 is 1.
Highest Common Factor of 523,902 is 1
Step 1: Since 902 > 523, we apply the division lemma to 902 and 523, to get
902 = 523 x 1 + 379
Step 2: Since the reminder 523 ≠ 0, we apply division lemma to 379 and 523, to get
523 = 379 x 1 + 144
Step 3: We consider the new divisor 379 and the new remainder 144, and apply the division lemma to get
379 = 144 x 2 + 91
We consider the new divisor 144 and the new remainder 91,and apply the division lemma to get
144 = 91 x 1 + 53
We consider the new divisor 91 and the new remainder 53,and apply the division lemma to get
91 = 53 x 1 + 38
We consider the new divisor 53 and the new remainder 38,and apply the division lemma to get
53 = 38 x 1 + 15
We consider the new divisor 38 and the new remainder 15,and apply the division lemma to get
38 = 15 x 2 + 8
We consider the new divisor 15 and the new remainder 8,and apply the division lemma to get
15 = 8 x 1 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 523 and 902 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(15,8) = HCF(38,15) = HCF(53,38) = HCF(91,53) = HCF(144,91) = HCF(379,144) = HCF(523,379) = HCF(902,523) .
