GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(801, 885) = 236295
GCD(801, 885) = ( 801 x 885 ) / 236295
= 801 / 885
= 801
Step2:
LCM(3, 138) = 138
GCD(3, 138) = ( 3 x 138 ) / 138
= 3 / 138
= 3
Step3:
LCM(3, 942) = 942
GCD(3, 942) = ( 3 x 942 ) / 942
= 3 / 942
= 3
So, Greatest Common Divisor of 801, 885, 138, 942 is 3
