HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 407, 520, 737 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 407, 520, 737 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 407, 520, 737 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 407, 520, 737 is 1.
HCF(407, 520, 737) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 407, 520, 737 is 1.
Step 1: Since 520 > 407, we apply the division lemma to 520 and 407, to get
520 = 407 x 1 + 113
Step 2: Since the reminder 407 ≠ 0, we apply division lemma to 113 and 407, to get
407 = 113 x 3 + 68
Step 3: We consider the new divisor 113 and the new remainder 68, and apply the division lemma to get
113 = 68 x 1 + 45
We consider the new divisor 68 and the new remainder 45,and apply the division lemma to get
68 = 45 x 1 + 23
We consider the new divisor 45 and the new remainder 23,and apply the division lemma to get
45 = 23 x 1 + 22
We consider the new divisor 23 and the new remainder 22,and apply the division lemma to get
23 = 22 x 1 + 1
We consider the new divisor 22 and the new remainder 1,and apply the division lemma to get
22 = 1 x 22 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 407 and 520 is 1
Notice that 1 = HCF(22,1) = HCF(23,22) = HCF(45,23) = HCF(68,45) = HCF(113,68) = HCF(407,113) = HCF(520,407) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 737 > 1, we apply the division lemma to 737 and 1, to get
737 = 1 x 737 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 737 is 1
Notice that 1 = HCF(737,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 407, 520, 737?
Answer: HCF of 407, 520, 737 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 407, 520, 737 using Euclid's Algorithm?
Answer: For arbitrary numbers 407, 520, 737 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
