HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 947, 637, 516 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 947, 637, 516 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 947, 637, 516 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 947, 637, 516 is 1.
HCF(947, 637, 516) = 1
HCF of 947, 637, 516 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 947, 637, 516 is 1.
Highest Common Factor of 947,637,516 is 1
Step 1: Since 947 > 637, we apply the division lemma to 947 and 637, to get
947 = 637 x 1 + 310
Step 2: Since the reminder 637 ≠ 0, we apply division lemma to 310 and 637, to get
637 = 310 x 2 + 17
Step 3: We consider the new divisor 310 and the new remainder 17, and apply the division lemma to get
310 = 17 x 18 + 4
We consider the new divisor 17 and the new remainder 4,and apply the division lemma to get
17 = 4 x 4 + 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 947 and 637 is 1
Notice that 1 = HCF(4,1) = HCF(17,4) = HCF(310,17) = HCF(637,310) = HCF(947,637) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 516 > 1, we apply the division lemma to 516 and 1, to get
516 = 1 x 516 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 516 is 1
Notice that 1 = HCF(516,1) .
