Given numbers are 172, 478, 607, 664
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(172, 478) = 41108
GCD(172, 478) = ( 172 x 478 ) / 41108
= 172 / 478
= 172
Step2:
LCM(2, 607) = 1214
GCD(2, 607) = ( 2 x 607 ) / 1214
= 2 / 607
= 2
Step3:
LCM(1, 664) = 664
GCD(1, 664) = ( 1 x 664 ) / 664
= 1 / 664
= 1
So, Greatest Common Divisor of 172, 478, 607, 664 is 1
