HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 688, 957, 732 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 688, 957, 732 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 688, 957, 732 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 688, 957, 732 is 1.
HCF(688, 957, 732) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 688, 957, 732 is 1.
Step 1: Since 957 > 688, we apply the division lemma to 957 and 688, to get
957 = 688 x 1 + 269
Step 2: Since the reminder 688 ≠ 0, we apply division lemma to 269 and 688, to get
688 = 269 x 2 + 150
Step 3: We consider the new divisor 269 and the new remainder 150, and apply the division lemma to get
269 = 150 x 1 + 119
We consider the new divisor 150 and the new remainder 119,and apply the division lemma to get
150 = 119 x 1 + 31
We consider the new divisor 119 and the new remainder 31,and apply the division lemma to get
119 = 31 x 3 + 26
We consider the new divisor 31 and the new remainder 26,and apply the division lemma to get
31 = 26 x 1 + 5
We consider the new divisor 26 and the new remainder 5,and apply the division lemma to get
26 = 5 x 5 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 688 and 957 is 1
Notice that 1 = HCF(5,1) = HCF(26,5) = HCF(31,26) = HCF(119,31) = HCF(150,119) = HCF(269,150) = HCF(688,269) = HCF(957,688) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 732 > 1, we apply the division lemma to 732 and 1, to get
732 = 1 x 732 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 732 is 1
Notice that 1 = HCF(732,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
