ANSWER

Use euclids algirithm to find H.C.F. of 1190 and 1445. Express the H.C.F. in the form of 1190m+1445n

Posted by Rohit Raj Yadav 6 years, 3 months ago

CBSE > Class 10 > Mathematics

1 answers

Neetu Yadav 6 years, 3 months ago

We know that HCF of two numbers can be found by Euclid's Division Algorithm

1445=1190×1+255

1190=255×4+170

255=170×1+85

170=85×2+0

so HCF(1190,1445) is 85

From second last equation

85=255-170

85=255-(1190-255×4)

85=255×5-1190

85=(1445-1190)×5-1190

85=-1190×6+1445×5

85=1190 m+1445n

m=-6

n=5

Hope it helps you.
