HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 954, 688, 666, 61 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 954, 688, 666, 61 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 954, 688, 666, 61 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 954, 688, 666, 61 is 1.
HCF(954, 688, 666, 61) = 1
HCF of 954, 688, 666, 61 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 954, 688, 666, 61 is 1.
Highest Common Factor of 954,688,666,61 is 1
Step 1: Since 954 > 688, we apply the division lemma to 954 and 688, to get
954 = 688 x 1 + 266
Step 2: Since the reminder 688 ≠ 0, we apply division lemma to 266 and 688, to get
688 = 266 x 2 + 156
Step 3: We consider the new divisor 266 and the new remainder 156, and apply the division lemma to get
266 = 156 x 1 + 110
We consider the new divisor 156 and the new remainder 110,and apply the division lemma to get
156 = 110 x 1 + 46
We consider the new divisor 110 and the new remainder 46,and apply the division lemma to get
110 = 46 x 2 + 18
We consider the new divisor 46 and the new remainder 18,and apply the division lemma to get
46 = 18 x 2 + 10
We consider the new divisor 18 and the new remainder 10,and apply the division lemma to get
18 = 10 x 1 + 8
We consider the new divisor 10 and the new remainder 8,and apply the division lemma to get
10 = 8 x 1 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 954 and 688 is 2
Notice that 2 = HCF(8,2) = HCF(10,8) = HCF(18,10) = HCF(46,18) = HCF(110,46) = HCF(156,110) = HCF(266,156) = HCF(688,266) = HCF(954,688) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 666 > 2, we apply the division lemma to 666 and 2, to get
666 = 2 x 333 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 666 is 2
Notice that 2 = HCF(666,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 61 > 2, we apply the division lemma to 61 and 2, to get
61 = 2 x 30 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 61 is 1
Notice that 1 = HCF(2,1) = HCF(61,2) .
