Given numbers are 128, 147, 190, 635
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(128, 147) = 18816
GCD(128, 147) = ( 128 x 147 ) / 18816
= 128 / 147
= 128
Step2:
LCM(1, 190) = 190
GCD(1, 190) = ( 1 x 190 ) / 190
= 1 / 190
= 1
Step3:
LCM(1, 635) = 635
GCD(1, 635) = ( 1 x 635 ) / 635
= 1 / 635
= 1
So, Greatest Common Divisor of 128, 147, 190, 635 is 1
