Given numbers are 664, 157, 642, 268
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(664, 157) = 104248
GCD(664, 157) = ( 664 x 157 ) / 104248
= 664 / 157
= 664
Step2:
LCM(1, 642) = 642
GCD(1, 642) = ( 1 x 642 ) / 642
= 1 / 642
= 1
Step3:
LCM(1, 268) = 268
GCD(1, 268) = ( 1 x 268 ) / 268
= 1 / 268
= 1
So, Greatest Common Divisor of 664, 157, 642, 268 is 1
