Given numbers are 207, 858, 358, 690
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(207, 858) = 59202
GCD(207, 858) = ( 207 x 858 ) / 59202
= 207 / 858
= 207
Step2:
LCM(3, 358) = 1074
GCD(3, 358) = ( 3 x 358 ) / 1074
= 3 / 358
= 3
Step3:
LCM(1, 690) = 690
GCD(1, 690) = ( 1 x 690 ) / 690
= 1 / 690
= 1
So, Greatest Common Divisor of 207, 858, 358, 690 is 1
