Given numbers are 898, 732, 100, 155
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(898, 732) = 328668
GCD(898, 732) = ( 898 x 732 ) / 328668
= 898 / 732
= 898
Step2:
LCM(2, 100) = 100
GCD(2, 100) = ( 2 x 100 ) / 100
= 2 / 100
= 2
Step3:
LCM(2, 155) = 310
GCD(2, 155) = ( 2 x 155 ) / 310
= 2 / 155
= 2
So, Greatest Common Divisor of 898, 732, 100, 155 is 1
