HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 207, 546, 62, 785 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 207, 546, 62, 785 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 207, 546, 62, 785 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 207, 546, 62, 785 is 1.
HCF(207, 546, 62, 785) = 1
HCF of 207, 546, 62, 785 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 207, 546, 62, 785 is 1.
Highest Common Factor of 207,546,62,785 is 1
Step 1: Since 546 > 207, we apply the division lemma to 546 and 207, to get
546 = 207 x 2 + 132
Step 2: Since the reminder 207 ≠ 0, we apply division lemma to 132 and 207, to get
207 = 132 x 1 + 75
Step 3: We consider the new divisor 132 and the new remainder 75, and apply the division lemma to get
132 = 75 x 1 + 57
We consider the new divisor 75 and the new remainder 57,and apply the division lemma to get
75 = 57 x 1 + 18
We consider the new divisor 57 and the new remainder 18,and apply the division lemma to get
57 = 18 x 3 + 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 207 and 546 is 3
Notice that 3 = HCF(18,3) = HCF(57,18) = HCF(75,57) = HCF(132,75) = HCF(207,132) = HCF(546,207) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 62 > 3, we apply the division lemma to 62 and 3, to get
62 = 3 x 20 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma 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 3 and 62 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(62,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 785 > 1, we apply the division lemma to 785 and 1, to get
785 = 1 x 785 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 785 is 1
Notice that 1 = HCF(785,1) .
