Given numbers are 915, 210, 791, 205
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(915, 210) = 12810
GCD(915, 210) = ( 915 x 210 ) / 12810
= 915 / 210
= 915
Step2:
LCM(15, 791) = 11865
GCD(15, 791) = ( 15 x 791 ) / 11865
= 15 / 791
= 15
Step3:
LCM(1, 205) = 205
GCD(1, 205) = ( 1 x 205 ) / 205
= 1 / 205
= 1
So, Greatest Common Divisor of 915, 210, 791, 205 is 1
