HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1918, 3561 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 1918, 3561 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 1918, 3561 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 1918, 3561 is 1.
HCF(1918, 3561) = 1
HCF of 1918, 3561 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1918, 3561 is 1.
Highest Common Factor of 1918,3561 is 1
Step 1: Since 3561 > 1918, we apply the division lemma to 3561 and 1918, to get
3561 = 1918 x 1 + 1643
Step 2: Since the reminder 1918 ≠ 0, we apply division lemma to 1643 and 1918, to get
1918 = 1643 x 1 + 275
Step 3: We consider the new divisor 1643 and the new remainder 275, and apply the division lemma to get
1643 = 275 x 5 + 268
We consider the new divisor 275 and the new remainder 268,and apply the division lemma to get
275 = 268 x 1 + 7
We consider the new divisor 268 and the new remainder 7,and apply the division lemma to get
268 = 7 x 38 + 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 1918 and 3561 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(268,7) = HCF(275,268) = HCF(1643,275) = HCF(1918,1643) = HCF(3561,1918) .
