HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 664, 239, 942 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 664, 239, 942 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 664, 239, 942 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 664, 239, 942 is 1.
HCF(664, 239, 942) = 1
HCF of 664, 239, 942 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 664, 239, 942 is 1.
Highest Common Factor of 664,239,942 is 1
Step 1: Since 664 > 239, we apply the division lemma to 664 and 239, to get
664 = 239 x 2 + 186
Step 2: Since the reminder 239 ≠ 0, we apply division lemma to 186 and 239, to get
239 = 186 x 1 + 53
Step 3: We consider the new divisor 186 and the new remainder 53, and apply the division lemma to get
186 = 53 x 3 + 27
We consider the new divisor 53 and the new remainder 27,and apply the division lemma to get
53 = 27 x 1 + 26
We consider the new divisor 27 and the new remainder 26,and apply the division lemma to get
27 = 26 x 1 + 1
We consider the new divisor 26 and the new remainder 1,and apply the division lemma to get
26 = 1 x 26 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 664 and 239 is 1
Notice that 1 = HCF(26,1) = HCF(27,26) = HCF(53,27) = HCF(186,53) = HCF(239,186) = HCF(664,239) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 942 > 1, we apply the division lemma to 942 and 1, to get
942 = 1 x 942 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 942 is 1
Notice that 1 = HCF(942,1) .
