HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 966, 690, 635 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 966, 690, 635 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 966, 690, 635 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 966, 690, 635 is 1.
HCF(966, 690, 635) = 1
HCF of 966, 690, 635 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 966, 690, 635 is 1.
Highest Common Factor of 966,690,635 is 1
Step 1: Since 966 > 690, we apply the division lemma to 966 and 690, to get
966 = 690 x 1 + 276
Step 2: Since the reminder 690 ≠ 0, we apply division lemma to 276 and 690, to get
690 = 276 x 2 + 138
Step 3: We consider the new divisor 276 and the new remainder 138, and apply the division lemma to get
276 = 138 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 138, the HCF of 966 and 690 is 138
Notice that 138 = HCF(276,138) = HCF(690,276) = HCF(966,690) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 635 > 138, we apply the division lemma to 635 and 138, to get
635 = 138 x 4 + 83
Step 2: Since the reminder 138 ≠ 0, we apply division lemma to 83 and 138, to get
138 = 83 x 1 + 55
Step 3: We consider the new divisor 83 and the new remainder 55, and apply the division lemma to get
83 = 55 x 1 + 28
We consider the new divisor 55 and the new remainder 28,and apply the division lemma to get
55 = 28 x 1 + 27
We consider the new divisor 28 and the new remainder 27,and apply the division lemma to get
28 = 27 x 1 + 1
We consider the new divisor 27 and the new remainder 1,and apply the division lemma to get
27 = 1 x 27 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 138 and 635 is 1
Notice that 1 = HCF(27,1) = HCF(28,27) = HCF(55,28) = HCF(83,55) = HCF(138,83) = HCF(635,138) .
