Given numbers are 705, 420, 879, 974
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(705, 420) = 19740
GCD(705, 420) = ( 705 x 420 ) / 19740
= 705 / 420
= 705
Step2:
LCM(15, 879) = 4395
GCD(15, 879) = ( 15 x 879 ) / 4395
= 15 / 879
= 15
Step3:
LCM(3, 974) = 2922
GCD(3, 974) = ( 3 x 974 ) / 2922
= 3 / 974
= 3
So, Greatest Common Divisor of 705, 420, 879, 974 is 1
