HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 720, 937, 429 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 720, 937, 429 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 720, 937, 429 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 720, 937, 429 is 1.
HCF(720, 937, 429) = 1
HCF of 720, 937, 429 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 720, 937, 429 is 1.
Highest Common Factor of 720,937,429 is 1
Step 1: Since 937 > 720, we apply the division lemma to 937 and 720, to get
937 = 720 x 1 + 217
Step 2: Since the reminder 720 ≠ 0, we apply division lemma to 217 and 720, to get
720 = 217 x 3 + 69
Step 3: We consider the new divisor 217 and the new remainder 69, and apply the division lemma to get
217 = 69 x 3 + 10
We consider the new divisor 69 and the new remainder 10,and apply the division lemma to get
69 = 10 x 6 + 9
We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get
10 = 9 x 1 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 720 and 937 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(69,10) = HCF(217,69) = HCF(720,217) = HCF(937,720) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 429 > 1, we apply the division lemma to 429 and 1, to get
429 = 1 x 429 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 429 is 1
Notice that 1 = HCF(429,1) .
