HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 608, 947, 983 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 608, 947, 983 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 608, 947, 983 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 608, 947, 983 is 1.
HCF(608, 947, 983) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 608, 947, 983 is 1.
Step 1: Since 947 > 608, we apply the division lemma to 947 and 608, to get
947 = 608 x 1 + 339
Step 2: Since the reminder 608 ≠ 0, we apply division lemma to 339 and 608, to get
608 = 339 x 1 + 269
Step 3: We consider the new divisor 339 and the new remainder 269, and apply the division lemma to get
339 = 269 x 1 + 70
We consider the new divisor 269 and the new remainder 70,and apply the division lemma to get
269 = 70 x 3 + 59
We consider the new divisor 70 and the new remainder 59,and apply the division lemma to get
70 = 59 x 1 + 11
We consider the new divisor 59 and the new remainder 11,and apply the division lemma to get
59 = 11 x 5 + 4
We consider the new divisor 11 and the new remainder 4,and apply the division lemma to get
11 = 4 x 2 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 608 and 947 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(59,11) = HCF(70,59) = HCF(269,70) = HCF(339,269) = HCF(608,339) = HCF(947,608) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 983 > 1, we apply the division lemma to 983 and 1, to get
983 = 1 x 983 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 983 is 1
Notice that 1 = HCF(983,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
