Question

Find out the greatest number that can divide 663 and 975

Answer 1

to find the greatest number which can divide663 and 975 we need to get HCF of these two
by Euclid division algorithm,
975=663*1+312
663=312*2+39
312=39*8+0

so, HCF of 663 and 975 is 39

Hence, greatest number which can divide 663 and 975 is 39
