HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 280, 959, 777 i.e. 7 the largest integer that leaves a remainder zero for all numbers.
HCF of 280, 959, 777 is 7 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 280, 959, 777 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 280, 959, 777 is 7.
HCF(280, 959, 777) = 7
HCF of 280, 959, 777 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 280, 959, 777 is 7.
Highest Common Factor of 280,959,777 is 7
Step 1: Since 959 > 280, we apply the division lemma to 959 and 280, to get
959 = 280 x 3 + 119
Step 2: Since the reminder 280 ≠ 0, we apply division lemma to 119 and 280, to get
280 = 119 x 2 + 42
Step 3: We consider the new divisor 119 and the new remainder 42, and apply the division lemma to get
119 = 42 x 2 + 35
We consider the new divisor 42 and the new remainder 35,and apply the division lemma to get
42 = 35 x 1 + 7
We consider the new divisor 35 and the new remainder 7,and apply the division lemma to get
35 = 7 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 280 and 959 is 7
Notice that 7 = HCF(35,7) = HCF(42,35) = HCF(119,42) = HCF(280,119) = HCF(959,280) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 777 > 7, we apply the division lemma to 777 and 7, to get
777 = 7 x 111 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 7 and 777 is 7
Notice that 7 = HCF(777,7) .
