Given numbers are 790, 755, 307, 218
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(790, 755) = 119290
GCD(790, 755) = ( 790 x 755 ) / 119290
= 790 / 755
= 790
Step2:
LCM(5, 307) = 1535
GCD(5, 307) = ( 5 x 307 ) / 1535
= 5 / 307
= 5
Step3:
LCM(1, 218) = 218
GCD(1, 218) = ( 1 x 218 ) / 218
= 1 / 218
= 1
So, Greatest Common Divisor of 790, 755, 307, 218 is 1
