Given numbers are 780, 945, 225, 970
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 945) = 49140
GCD(780, 945) = ( 780 x 945 ) / 49140
= 780 / 945
= 780
Step2:
LCM(15, 225) = 225
GCD(15, 225) = ( 15 x 225 ) / 225
= 15 / 225
= 15
Step3:
LCM(15, 970) = 2910
GCD(15, 970) = ( 15 x 970 ) / 2910
= 15 / 970
= 15
So, Greatest Common Divisor of 780, 945, 225, 970 is 5
