Given numbers are 172, 213, 242, 668
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(172, 213) = 36636
GCD(172, 213) = ( 172 x 213 ) / 36636
= 172 / 213
= 172
Step2:
LCM(1, 242) = 242
GCD(1, 242) = ( 1 x 242 ) / 242
= 1 / 242
= 1
Step3:
LCM(1, 668) = 668
GCD(1, 668) = ( 1 x 668 ) / 668
= 1 / 668
= 1
So, Greatest Common Divisor of 172, 213, 242, 668 is 1
