GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(513, 639) = 36423
GCD(513, 639) = ( 513 x 639 ) / 36423
= 513 / 639
= 513
Step2:
LCM(9, 690) = 2070
GCD(9, 690) = ( 9 x 690 ) / 2070
= 9 / 690
= 9
Step3:
LCM(3, 147) = 147
GCD(3, 147) = ( 3 x 147 ) / 147
= 3 / 147
= 3
So, Greatest Common Divisor of 513, 639, 690, 147 is 3
