HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1561, 9228 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 1561, 9228 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 1561, 9228 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 1561, 9228 is 1.
HCF(1561, 9228) = 1
HCF of 1561, 9228 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1561, 9228 is 1.
Highest Common Factor of 1561,9228 is 1
Step 1: Since 9228 > 1561, we apply the division lemma to 9228 and 1561, to get
9228 = 1561 x 5 + 1423
Step 2: Since the reminder 1561 ≠ 0, we apply division lemma to 1423 and 1561, to get
1561 = 1423 x 1 + 138
Step 3: We consider the new divisor 1423 and the new remainder 138, and apply the division lemma to get
1423 = 138 x 10 + 43
We consider the new divisor 138 and the new remainder 43,and apply the division lemma to get
138 = 43 x 3 + 9
We consider the new divisor 43 and the new remainder 9,and apply the division lemma to get
43 = 9 x 4 + 7
We consider the new divisor 9 and the new remainder 7,and apply the division lemma to get
9 = 7 x 1 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1561 and 9228 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(43,9) = HCF(138,43) = HCF(1423,138) = HCF(1561,1423) = HCF(9228,1561) .
