Given numbers are 805, 133, 455, 972
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(805, 133) = 15295
GCD(805, 133) = ( 805 x 133 ) / 15295
= 805 / 133
= 805
Step2:
LCM(7, 455) = 455
GCD(7, 455) = ( 7 x 455 ) / 455
= 7 / 455
= 7
Step3:
LCM(7, 972) = 6804
GCD(7, 972) = ( 7 x 972 ) / 6804
= 7 / 972
= 7
So, Greatest Common Divisor of 805, 133, 455, 972 is 1
