HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 780, 446 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 780, 446 is 2 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, 446 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, 446 is 2.
HCF(780, 446) = 2
HCF of 780, 446 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, 446 is 2.
Highest Common Factor of 780,446 is 2
Step 1: Since 780 > 446, we apply the division lemma to 780 and 446, to get
780 = 446 x 1 + 334
Step 2: Since the reminder 446 ≠ 0, we apply division lemma to 334 and 446, to get
446 = 334 x 1 + 112
Step 3: We consider the new divisor 334 and the new remainder 112, and apply the division lemma to get
334 = 112 x 2 + 110
We consider the new divisor 112 and the new remainder 110,and apply the division lemma to get
112 = 110 x 1 + 2
We consider the new divisor 110 and the new remainder 2,and apply the division lemma to get
110 = 2 x 55 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 780 and 446 is 2
Notice that 2 = HCF(110,2) = HCF(112,110) = HCF(334,112) = HCF(446,334) = HCF(780,446) .
