HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 693, 352, 72, 149 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 693, 352, 72, 149 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 693, 352, 72, 149 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 693, 352, 72, 149 is 1.
HCF(693, 352, 72, 149) = 1
HCF of 693, 352, 72, 149 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 693, 352, 72, 149 is 1.
Highest Common Factor of 693,352,72,149 is 1
Step 1: Since 693 > 352, we apply the division lemma to 693 and 352, to get
693 = 352 x 1 + 341
Step 2: Since the reminder 352 ≠ 0, we apply division lemma to 341 and 352, to get
352 = 341 x 1 + 11
Step 3: We consider the new divisor 341 and the new remainder 11, and apply the division lemma to get
341 = 11 x 31 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 693 and 352 is 11
Notice that 11 = HCF(341,11) = HCF(352,341) = HCF(693,352) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 72 > 11, we apply the division lemma to 72 and 11, to get
72 = 11 x 6 + 6
Step 2: Since the reminder 11 ≠ 0, we apply division lemma to 6 and 11, to get
11 = 6 x 1 + 5
Step 3: We consider the new divisor 6 and the new remainder 5, and apply the division lemma to get
6 = 5 x 1 + 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 11 and 72 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(72,11) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 149 > 1, we apply the division lemma to 149 and 1, to get
149 = 1 x 149 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 149 is 1
Notice that 1 = HCF(149,1) .
