Given numbers are 810, 237, 542, 643
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(810, 237) = 63990
GCD(810, 237) = ( 810 x 237 ) / 63990
= 810 / 237
= 810
Step2:
LCM(3, 542) = 1626
GCD(3, 542) = ( 3 x 542 ) / 1626
= 3 / 542
= 3
Step3:
LCM(1, 643) = 643
GCD(1, 643) = ( 1 x 643 ) / 643
= 1 / 643
= 1
So, Greatest Common Divisor of 810, 237, 542, 643 is 1
