HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 141, 645, 280 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 141, 645, 280 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 141, 645, 280 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 141, 645, 280 is 1.
HCF(141, 645, 280) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 141, 645, 280 is 1.
Step 1: Since 645 > 141, we apply the division lemma to 645 and 141, to get
645 = 141 x 4 + 81
Step 2: Since the reminder 141 ≠ 0, we apply division lemma to 81 and 141, to get
141 = 81 x 1 + 60
Step 3: We consider the new divisor 81 and the new remainder 60, and apply the division lemma to get
81 = 60 x 1 + 21
We consider the new divisor 60 and the new remainder 21,and apply the division lemma to get
60 = 21 x 2 + 18
We consider the new divisor 21 and the new remainder 18,and apply the division lemma to get
21 = 18 x 1 + 3
We consider the new divisor 18 and the new remainder 3,and apply the division lemma to get
18 = 3 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 141 and 645 is 3
Notice that 3 = HCF(18,3) = HCF(21,18) = HCF(60,21) = HCF(81,60) = HCF(141,81) = HCF(645,141) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 280 > 3, we apply the division lemma to 280 and 3, to get
280 = 3 x 93 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 280 is 1
Notice that 1 = HCF(3,1) = HCF(280,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 141, 645, 280?
Answer: HCF of 141, 645, 280 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 141, 645, 280 using Euclid's Algorithm?
Answer: For arbitrary numbers 141, 645, 280 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
