Given numbers are 784, 520, 165, 437
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(784, 520) = 50960
GCD(784, 520) = ( 784 x 520 ) / 50960
= 784 / 520
= 784
Step2:
LCM(8, 165) = 1320
GCD(8, 165) = ( 8 x 165 ) / 1320
= 8 / 165
= 8
Step3:
LCM(1, 437) = 437
GCD(1, 437) = ( 1 x 437 ) / 437
= 1 / 437
= 1
So, Greatest Common Divisor of 784, 520, 165, 437 is 1
