Given numbers are 945, 981, 830, 220
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(945, 981) = 103005
GCD(945, 981) = ( 945 x 981 ) / 103005
= 945 / 981
= 945
Step2:
LCM(9, 830) = 7470
GCD(9, 830) = ( 9 x 830 ) / 7470
= 9 / 830
= 9
Step3:
LCM(1, 220) = 220
GCD(1, 220) = ( 1 x 220 ) / 220
= 1 / 220
= 1
So, Greatest Common Divisor of 945, 981, 830, 220 is 1
