HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 654, 787 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 654, 787 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 654, 787 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 654, 787 is 1.
HCF(654, 787) = 1
HCF of 654, 787 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 654, 787 is 1.
Highest Common Factor of 654,787 is 1
Step 1: Since 787 > 654, we apply the division lemma to 787 and 654, to get
787 = 654 x 1 + 133
Step 2: Since the reminder 654 ≠ 0, we apply division lemma to 133 and 654, to get
654 = 133 x 4 + 122
Step 3: We consider the new divisor 133 and the new remainder 122, and apply the division lemma to get
133 = 122 x 1 + 11
We consider the new divisor 122 and the new remainder 11,and apply the division lemma to get
122 = 11 x 11 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 654 and 787 is 1
Notice that 1 = HCF(11,1) = HCF(122,11) = HCF(133,122) = HCF(654,133) = HCF(787,654) .
