Given numbers are 213, 630, 849, 340
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(213, 630) = 44730
GCD(213, 630) = ( 213 x 630 ) / 44730
= 213 / 630
= 213
Step2:
LCM(3, 849) = 849
GCD(3, 849) = ( 3 x 849 ) / 849
= 3 / 849
= 3
Step3:
LCM(3, 340) = 1020
GCD(3, 340) = ( 3 x 340 ) / 1020
= 3 / 340
= 3
So, Greatest Common Divisor of 213, 630, 849, 340 is 1
