HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 765, 901, 654 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 765, 901, 654 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 765, 901, 654 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 765, 901, 654 is 1.
HCF(765, 901, 654) = 1
HCF of 765, 901, 654 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 765, 901, 654 is 1.
Highest Common Factor of 765,901,654 is 1
Step 1: Since 901 > 765, we apply the division lemma to 901 and 765, to get
901 = 765 x 1 + 136
Step 2: Since the reminder 765 ≠ 0, we apply division lemma to 136 and 765, to get
765 = 136 x 5 + 85
Step 3: We consider the new divisor 136 and the new remainder 85, and apply the division lemma to get
136 = 85 x 1 + 51
We consider the new divisor 85 and the new remainder 51,and apply the division lemma to get
85 = 51 x 1 + 34
We consider the new divisor 51 and the new remainder 34,and apply the division lemma to get
51 = 34 x 1 + 17
We consider the new divisor 34 and the new remainder 17,and apply the division lemma to get
34 = 17 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 17, the HCF of 765 and 901 is 17
Notice that 17 = HCF(34,17) = HCF(51,34) = HCF(85,51) = HCF(136,85) = HCF(765,136) = HCF(901,765) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 654 > 17, we apply the division lemma to 654 and 17, to get
654 = 17 x 38 + 8
Step 2: Since the reminder 17 ≠ 0, we apply division lemma to 8 and 17, to get
17 = 8 x 2 + 1
Step 3: We consider the new divisor 8 and the new remainder 1, and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 17 and 654 is 1
Notice that 1 = HCF(8,1) = HCF(17,8) = HCF(654,17) .
