Given numbers are 945, 447, 475, 840
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(945, 447) = 140805
GCD(945, 447) = ( 945 x 447 ) / 140805
= 945 / 447
= 945
Step2:
LCM(3, 475) = 1425
GCD(3, 475) = ( 3 x 475 ) / 1425
= 3 / 475
= 3
Step3:
LCM(1, 840) = 840
GCD(1, 840) = ( 1 x 840 ) / 840
= 1 / 840
= 1
So, Greatest Common Divisor of 945, 447, 475, 840 is 1
