Given numbers are 801, 249, 104, 660
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(801, 249) = 66483
GCD(801, 249) = ( 801 x 249 ) / 66483
= 801 / 249
= 801
Step2:
LCM(3, 104) = 312
GCD(3, 104) = ( 3 x 104 ) / 312
= 3 / 104
= 3
Step3:
LCM(1, 660) = 660
GCD(1, 660) = ( 1 x 660 ) / 660
= 1 / 660
= 1
So, Greatest Common Divisor of 801, 249, 104, 660 is 1
