HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 621, 979, 544, 698 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 621, 979, 544, 698 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 621, 979, 544, 698 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 621, 979, 544, 698 is 1.
HCF(621, 979, 544, 698) = 1
HCF of 621, 979, 544, 698 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 621, 979, 544, 698 is 1.
Highest Common Factor of 621,979,544,698 is 1
Step 1: Since 979 > 621, we apply the division lemma to 979 and 621, to get
979 = 621 x 1 + 358
Step 2: Since the reminder 621 ≠ 0, we apply division lemma to 358 and 621, to get
621 = 358 x 1 + 263
Step 3: We consider the new divisor 358 and the new remainder 263, and apply the division lemma to get
358 = 263 x 1 + 95
We consider the new divisor 263 and the new remainder 95,and apply the division lemma to get
263 = 95 x 2 + 73
We consider the new divisor 95 and the new remainder 73,and apply the division lemma to get
95 = 73 x 1 + 22
We consider the new divisor 73 and the new remainder 22,and apply the division lemma to get
73 = 22 x 3 + 7
We consider the new divisor 22 and the new remainder 7,and apply the division lemma to get
22 = 7 x 3 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 621 and 979 is 1
Notice that 1 = HCF(7,1) = HCF(22,7) = HCF(73,22) = HCF(95,73) = HCF(263,95) = HCF(358,263) = HCF(621,358) = HCF(979,621) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 544 > 1, we apply the division lemma to 544 and 1, to get
544 = 1 x 544 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 544 is 1
Notice that 1 = HCF(544,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 698 > 1, we apply the division lemma to 698 and 1, to get
698 = 1 x 698 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 698 is 1
Notice that 1 = HCF(698,1) .
