Given numbers are 443, 612, 261, 490
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(443, 612) = 271116
GCD(443, 612) = ( 443 x 612 ) / 271116
= 443 / 612
= 443
Step2:
LCM(1, 261) = 261
GCD(1, 261) = ( 1 x 261 ) / 261
= 1 / 261
= 1
Step3:
LCM(1, 490) = 490
GCD(1, 490) = ( 1 x 490 ) / 490
= 1 / 490
= 1
So, Greatest Common Divisor of 443, 612, 261, 490 is 1
