Given numbers are 105, 235, 661, 974
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(105, 235) = 4935
GCD(105, 235) = ( 105 x 235 ) / 4935
= 105 / 235
= 105
Step2:
LCM(5, 661) = 3305
GCD(5, 661) = ( 5 x 661 ) / 3305
= 5 / 661
= 5
Step3:
LCM(1, 974) = 974
GCD(1, 974) = ( 1 x 974 ) / 974
= 1 / 974
= 1
So, Greatest Common Divisor of 105, 235, 661, 974 is 1
