The GCF is 25.
The GCF is 25.
200 = 23 x 52 175 = 52 x 7 hcf = 52 = 25 lcm = 23 x 52 x 7 = 1400
Factors of 16 are 1,2,4,8 & 16... Factors of 25 are 1,5 & 25. Therefore the HCF is 1 !
The GCF is 7.
The GCF is 25.
The GCF is 25.
The HCF of 25 and 50 is... 25.
175 = 7 x 25, 625 = 25 x 25 so HCF is 25
25
The HCF is 5.
200 = 23 x 52 175 = 52 x 7 hcf = 52 = 25 lcm = 23 x 52 x 7 = 1400
The HCF is 7.
