HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 765, 370, 236, 150 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 765, 370, 236, 150 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 765, 370, 236, 150 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 765, 370, 236, 150 is 1.
HCF(765, 370, 236, 150) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 765, 370, 236, 150 is 1.
Step 1: Since 765 > 370, we apply the division lemma to 765 and 370, to get
765 = 370 x 2 + 25
Step 2: Since the reminder 370 ≠ 0, we apply division lemma to 25 and 370, to get
370 = 25 x 14 + 20
Step 3: We consider the new divisor 25 and the new remainder 20, and apply the division lemma to get
25 = 20 x 1 + 5
We consider the new divisor 20 and the new remainder 5, and apply the division lemma to get
20 = 5 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 765 and 370 is 5
Notice that 5 = HCF(20,5) = HCF(25,20) = HCF(370,25) = HCF(765,370) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 236 > 5, we apply the division lemma to 236 and 5, to get
236 = 5 x 47 + 1
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 1 and 5, to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 236 is 1
Notice that 1 = HCF(5,1) = HCF(236,5) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 150 > 1, we apply the division lemma to 150 and 1, to get
150 = 1 x 150 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 150 is 1
Notice that 1 = HCF(150,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 765, 370, 236, 150?
Answer: HCF of 765, 370, 236, 150 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 765, 370, 236, 150 using Euclid's Algorithm?
Answer: For arbitrary numbers 765, 370, 236, 150 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
