Given numbers are 648, 900, 639, 262
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(648, 900) = 16200
GCD(648, 900) = ( 648 x 900 ) / 16200
= 648 / 900
= 648
Step2:
LCM(36, 639) = 2556
GCD(36, 639) = ( 36 x 639 ) / 2556
= 36 / 639
= 36
Step3:
LCM(9, 262) = 2358
GCD(9, 262) = ( 9 x 262 ) / 2358
= 9 / 262
= 9
So, Greatest Common Divisor of 648, 900, 639, 262 is 1
