Given numbers are 345, 212, 77, 662
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(345, 212) = 73140
GCD(345, 212) = ( 345 x 212 ) / 73140
= 345 / 212
= 345
Step2:
LCM(1, 77) = 77
GCD(1, 77) = ( 1 x 77 ) / 77
= 1 / 77
= 1
Step3:
LCM(1, 662) = 662
GCD(1, 662) = ( 1 x 662 ) / 662
= 1 / 662
= 1
So, Greatest Common Divisor of 345, 212, 77, 662 is 1
