Given numbers are 120, 870, 252, 825
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(120, 870) = 3480
GCD(120, 870) = ( 120 x 870 ) / 3480
= 120 / 870
= 120
Step2:
LCM(30, 252) = 1260
GCD(30, 252) = ( 30 x 252 ) / 1260
= 30 / 252
= 30
Step3:
LCM(6, 825) = 1650
GCD(6, 825) = ( 6 x 825 ) / 1650
= 6 / 825
= 6
So, Greatest Common Divisor of 120, 870, 252, 825 is 3
