Given numbers are 213, 338, 715, 790
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(213, 338) = 71994
GCD(213, 338) = ( 213 x 338 ) / 71994
= 213 / 338
= 213
Step2:
LCM(1, 715) = 715
GCD(1, 715) = ( 1 x 715 ) / 715
= 1 / 715
= 1
Step3:
LCM(1, 790) = 790
GCD(1, 790) = ( 1 x 790 ) / 790
= 1 / 790
= 1
So, Greatest Common Divisor of 213, 338, 715, 790 is 1
