HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 780, 623 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 780, 623 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 780, 623 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 780, 623 is 1.
HCF(780, 623) = 1
HCF of 780, 623 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 780, 623 is 1.
Highest Common Factor of 780,623 is 1
Step 1: Since 780 > 623, we apply the division lemma to 780 and 623, to get
780 = 623 x 1 + 157
Step 2: Since the reminder 623 ≠ 0, we apply division lemma to 157 and 623, to get
623 = 157 x 3 + 152
Step 3: We consider the new divisor 157 and the new remainder 152, and apply the division lemma to get
157 = 152 x 1 + 5
We consider the new divisor 152 and the new remainder 5,and apply the division lemma to get
152 = 5 x 30 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
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 780 and 623 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(152,5) = HCF(157,152) = HCF(623,157) = HCF(780,623) .
