Given numbers are 180, 898, 830, 945
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(180, 898) = 80820
GCD(180, 898) = ( 180 x 898 ) / 80820
= 180 / 898
= 180
Step2:
LCM(2, 830) = 830
GCD(2, 830) = ( 2 x 830 ) / 830
= 2 / 830
= 2
Step3:
LCM(2, 945) = 1890
GCD(2, 945) = ( 2 x 945 ) / 1890
= 2 / 945
= 2
So, Greatest Common Divisor of 180, 898, 830, 945 is 1
