HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 153, 669, 268, 706 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 153, 669, 268, 706 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 153, 669, 268, 706 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 153, 669, 268, 706 is 1.
HCF(153, 669, 268, 706) = 1
HCF of 153, 669, 268, 706 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 153, 669, 268, 706 is 1.
Highest Common Factor of 153,669,268,706 is 1
Step 1: Since 669 > 153, we apply the division lemma to 669 and 153, to get
669 = 153 x 4 + 57
Step 2: Since the reminder 153 ≠ 0, we apply division lemma to 57 and 153, to get
153 = 57 x 2 + 39
Step 3: We consider the new divisor 57 and the new remainder 39, and apply the division lemma to get
57 = 39 x 1 + 18
We consider the new divisor 39 and the new remainder 18,and apply the division lemma to get
39 = 18 x 2 + 3
We consider the new divisor 18 and the new remainder 3,and apply the division lemma to get
18 = 3 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 153 and 669 is 3
Notice that 3 = HCF(18,3) = HCF(39,18) = HCF(57,39) = HCF(153,57) = HCF(669,153) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 268 > 3, we apply the division lemma to 268 and 3, to get
268 = 3 x 89 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 268 is 1
Notice that 1 = HCF(3,1) = HCF(268,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 706 > 1, we apply the division lemma to 706 and 1, to get
706 = 1 x 706 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 706 is 1
Notice that 1 = HCF(706,1) .
