Given numbers are 648, 442, 660, 893
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(648, 442) = 143208
GCD(648, 442) = ( 648 x 442 ) / 143208
= 648 / 442
= 648
Step2:
LCM(2, 660) = 660
GCD(2, 660) = ( 2 x 660 ) / 660
= 2 / 660
= 2
Step3:
LCM(2, 893) = 1786
GCD(2, 893) = ( 2 x 893 ) / 1786
= 2 / 893
= 2
So, Greatest Common Divisor of 648, 442, 660, 893 is 1
