Given numbers are 815, 868, 525, 225
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(815, 868) = 707420
GCD(815, 868) = ( 815 x 868 ) / 707420
= 815 / 868
= 815
Step2:
LCM(1, 525) = 525
GCD(1, 525) = ( 1 x 525 ) / 525
= 1 / 525
= 1
Step3:
LCM(1, 225) = 225
GCD(1, 225) = ( 1 x 225 ) / 225
= 1 / 225
= 1
So, Greatest Common Divisor of 815, 868, 525, 225 is 1
