HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 660, 907, 730 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 660, 907, 730 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 660, 907, 730 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 660, 907, 730 is 1.
HCF(660, 907, 730) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 660, 907, 730 is 1.
Step 1: Since 907 > 660, we apply the division lemma to 907 and 660, to get
907 = 660 x 1 + 247
Step 2: Since the reminder 660 ≠ 0, we apply division lemma to 247 and 660, to get
660 = 247 x 2 + 166
Step 3: We consider the new divisor 247 and the new remainder 166, and apply the division lemma to get
247 = 166 x 1 + 81
We consider the new divisor 166 and the new remainder 81,and apply the division lemma to get
166 = 81 x 2 + 4
We consider the new divisor 81 and the new remainder 4,and apply the division lemma to get
81 = 4 x 20 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 660 and 907 is 1
Notice that 1 = HCF(4,1) = HCF(81,4) = HCF(166,81) = HCF(247,166) = HCF(660,247) = HCF(907,660) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 730 > 1, we apply the division lemma to 730 and 1, to get
730 = 1 x 730 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 730 is 1
Notice that 1 = HCF(730,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 660, 907, 730?
Answer: HCF of 660, 907, 730 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 660, 907, 730 using Euclid's Algorithm?
Answer: For arbitrary numbers 660, 907, 730 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
