Given numbers are 972, 530, 147, 153
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(972, 530) = 257580
GCD(972, 530) = ( 972 x 530 ) / 257580
= 972 / 530
= 972
Step2:
LCM(2, 147) = 294
GCD(2, 147) = ( 2 x 147 ) / 294
= 2 / 147
= 2
Step3:
LCM(1, 153) = 153
GCD(1, 153) = ( 1 x 153 ) / 153
= 1 / 153
= 1
So, Greatest Common Divisor of 972, 530, 147, 153 is 1
