HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 369, 890, 121 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 369, 890, 121 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 369, 890, 121 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 369, 890, 121 is 1.
HCF(369, 890, 121) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 369, 890, 121 is 1.
Step 1: Since 890 > 369, we apply the division lemma to 890 and 369, to get
890 = 369 x 2 + 152
Step 2: Since the reminder 369 ≠ 0, we apply division lemma to 152 and 369, to get
369 = 152 x 2 + 65
Step 3: We consider the new divisor 152 and the new remainder 65, and apply the division lemma to get
152 = 65 x 2 + 22
We consider the new divisor 65 and the new remainder 22,and apply the division lemma to get
65 = 22 x 2 + 21
We consider the new divisor 22 and the new remainder 21,and apply the division lemma to get
22 = 21 x 1 + 1
We consider the new divisor 21 and the new remainder 1,and apply the division lemma to get
21 = 1 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 369 and 890 is 1
Notice that 1 = HCF(21,1) = HCF(22,21) = HCF(65,22) = HCF(152,65) = HCF(369,152) = HCF(890,369) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 121 > 1, we apply the division lemma to 121 and 1, to get
121 = 1 x 121 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 121 is 1
Notice that 1 = HCF(121,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 369, 890, 121?
Answer: HCF of 369, 890, 121 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 369, 890, 121 using Euclid's Algorithm?
Answer: For arbitrary numbers 369, 890, 121 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
